DIY repair of aluminum tubes of a car air conditioner

In detail: do-it-yourself repair of aluminum tubes of a car air conditioner from a real master for the site my.housecope.com.

The repair of the air conditioner pipes can be carried out both for the reason that they have broken, and for the reason that they are dirty and cannot be cleaned. In winter, when the air conditioner is not working, aluminum hoses and pipes can become clogged, especially in the gaps between the engine radiator and the air conditioner radiator. Contaminants can accumulate and can contaminate the lines. And all this together can impede the correct circulation of the refrigerant and mixing of refrigerant and moisture is simply inevitable.

The tubes themselves are made of aluminum, so external factors can destructively affect this material. Temperature extremes, violation of moisture levels, the presence of reagents - all this can lead to the destruction of aluminum. And besides this, there are O-rings and rubber gaskets, which, under the influence of various factors, can deteriorate even faster.

The performance of aluminum tubes is affected by the country's climate, temperature regime, road surface or its absence, general loads on the car and getting into road accidents.

All this negatively affects the operation of the cooling unit, and as a result, the repair of the air conditioning pipes is simply inevitable.

You might mistakenly think that nothing depends on the performance of the tubes, but how long the autoconditioner tubes are repaired will depend on its durability. Tightening can provoke the compressor to depressurize and a complete replacement of the device will have to be performed. Worst of all, if in the process of wear and tear, the car owner does not notice this and the climate system becomes contaminated with particles of compression rings. In this case, not only the entire system is endangered, but also the health of the car passengers will be disrupted. Many have already felt that the cooling system can cause real health problems.

Repairing air conditioner pipes is easy if the cracks are very small, which are barely visible to the eye. In this case, you can not use argon-arc welding, but use special compounds. The so-called soldering of holes in the form of patches is performed. It is possible to apply such mixtures in several layers so that their thickness is 2-3 millimeters. Thus, we achieve a quality car air conditioner repair.

Welding the tubes of the air conditioner will be required if the size of the cracks exceeds the norm of 2-3 millimeters. In this case, we will acquire argon-arc welding and go ahead to work.

Soldering the tube of the auto air conditioner

If you want to save a lot on repairing the air conditioner pipes, you will have to do it yourself. I want to note that this still requires soldering experience, albeit a little. It is important to stock up on a specific tool: a pipe cutter, a special bending machine and welding. Please note that the pipe cutter can also be replaced with a metal file, but this will not be the quality that we expect in the repair of air conditioner pipes.

The pipe bender can be either universal (for different diameters) or specific (for a specific diameter). When choosing this tool, it is worth knowing what dimensions are used in your machine. Often it is 6, 8, 10 sizes, which corresponds to the inner diameter in millimeters. You can see the size on the vehicle system or in the technical documentation.This is a fundamentally important repair issue because different machines use different measuring systems.

Repair of auto-air conditioner pipes begins with the fact that you need to buy or make parts. Next, we cut off the required length and bend them using a bending machine. When the tubes are ready, we cut the fittings and connect it all into a single system. Before soldering, it is worth rewinding the parts with electrical tape and see if you did everything right. If everything fits, then we start soldering.

When repairing the tubes of an auto-air conditioner, it is not always possible to resort to the above method. Sometimes the tubes of the air conditioner are replaced with hoses that are made of rubber. Although they are made of less durable material, replacing them will be very quick, simple and cheap. Welding of the air conditioner pipes is not used here, usually the hoses are screwed in.

Welding of the tubes of the air conditioner is also used if they are made of copper. The copper type of joints is more durable than aluminum, but it is expensive. In this case, it is necessary to perform flaring work. And this is a job for professionals with a high-quality specific tool (it is present only at good service stations). Sometimes for such parts, insulation is performed, which saves from freezing in winter and performs thermal insulation of the system.

At the end of the article, I would like to note that you need to closely monitor the cooling system: listen to the sounds in the operation of devices, to smells and to the general characteristics of performance. All this can tell you in time about problems that are easy to fix in the first stages. Take good care of your car and it will serve you for many years!

On the recording, an auto expert shows how to properly solder a copper pipe of an automobile air conditioner.

The air conditioning system consists of many elements that can wear out over time and lose their primary functions. One of these is the pipes through which cold air and gas is transmitted, which are necessary for the normal operation of the condender. In what cases are car air conditioner pipes repaired and how to do this task with your own hands - find out from this article.

The need to repair the air conditioner tubes may arise as a result of their breakage or contamination. Moreover, the contamination can be so serious that the hoses themselves are no longer subject to cleaning. In the cold season, when the condender practically does not turn on, the system lines can become clogged, especially dirt collects in the area between the radiator devices of the motor and the air conditioner. Accordingly, contamination of the air conditioning pipes of the car can interfere with the optimal circulation of the consumable, which will subsequently lead to the mixing of freon and moisture.

Air conditioning lines are usually made of aluminum, respectively, various external factors can negatively affect this material. Due to temperature extremes, a violation of the moisture level, as well as the presence of various reagents, aluminum can simply collapse. In addition, the pipes of the system are also equipped with gaskets and seals, which, in turn, also break down, only even stronger and faster. The service life of the tubes depends on many factors - the conditions for using the car, the climate of the region, temperature, loads on the car as a whole..

So, for what reasons the tubes fail:

due to temperature extremes;
as a result of exposure to road reagents;
due to clogging;
due to changes in humidity;
as a result of severe frosts;
when the car gets into an accident.

If hoses are being repaired for car air conditioners, then, as a rule, cracks can be patched using argon arc welding. In particular, if the cracks are large enough.As for the smaller damages, you can get rid of them without a welding machine. To remove such damage, you can use special compounds, which must be sprayed onto the surface of the tube in several layers. It is desirable that when welding the tubes of the conditioner, the total thickness of the patches is about 2-3 mm.

It should also be borne in mind that usually the process of producing new pipes for the condenser is much cheaper for the car owner than purchasing them. For manufacturing, it is important to correctly calculate all dimensions and prepare the necessary tool. So that the production process does not cause difficulties, it is necessary to prepare in advance a high-quality pipe cutter, as well as a pipe bender. The first will allow you to cut the edges of the pipe with the highest quality, and the second can be used, if necessary, to bend the pipe at an angle (video author - Denis Chesnokov).

If you decide to repair the hoses, then first of all you need to decide - you will buy parts or make them yourself. During production, you need to be careful and correctly measure in accordance with the technical documentation for the machine. In practice, our compatriots quite often confuse meters with inches, as a result of which the repair procedure can be difficult.

A few points to consider when carrying out repairs:

In any case, if you want the air conditioning system to work for a long time and without complaints, its condition should be monitored, especially during the off-season. You should always pay attention to the sounds that appear during the operation of the air conditioner, as well as smells that may come from the blowers. Of course, you also need to pay attention to the efficiency of the system - if you notice that the condender has become less efficient, this may indicate various malfunctions. Moreover, as practice shows, most often it is better to eliminate them at the initial stages.

The video below shows the process of repairing the hoses of an automobile air conditioner (video author - Tim Service channel).

The connection of the units of any air conditioner is carried out by pipes and high pressure hoses.

Any destruction of the pipeline causes the leakage of freon and breakdown of the "heart" of the air conditioner - the compressor.

Repairing a high-pressure pipe of an air conditioner is not a difficult process, but it can only be done using special equipment.

Welding of cracks and loose seams is possible only in argon and is carried out by argon-arc welding.

Diagnostics is carried out when the air conditioner fails.

It is practically impossible to independently determine the state of the pipeline. Freon leakage can occur through microcracks formed in high-pressure pipes or hoses. They are not noticeable to the eye, and freon is colorless. You will not see it without special detection devices. Specialized service stations have equipment that allows you to accurately determine the place of refrigerant leakage.

Sequence

diagnostics:

visual inspection;
measurement of freon pressure in the system;
determination of the place of destruction of the tube by a leak detector;
ultraviolet diagnostics.

As you can see, the diagnostic process requires special equipment. There is no way to independently detect the place of leakage of freon from a tube or hose. Such equipment for pipeline diagnostics is available at our service.

Repairing aluminum tubes for an air conditioner on a car is a problem that every car enthusiast has to face. Some people try to do it on their own. True, in most cases, they still have to seek help at the service station and fix what was done with their own hands. The process of restoring aluminum pipes is carried out in two ways - by welding cracks and spraying several layers of a special composite on microcracks.

In argon arc welding, the entire

the welded surface of the tube section is in an inert gas medium - argon. It is not possible to weld aluminum without it. The work is carried out with a special welding machine designed for welding non-ferrous metals.

If the crack is small, barely visible to the eye, it is sealed. A special composite is applied in layers to the crack. When the total layer thickness reaches 3 mm, the work is completed.

Depending on the damage during the diagnosis, a decision is made on how to eliminate it. A situation may arise when replacement becomes more expedient and cheaper for the client than welding or soldering the tubes of the car air conditioner.

Defective rubber hoses must be replaced. On the Internet you can find advice from "craftsmen" on the issue of repairing a hose with your own hands, but you should not do this, since rubber is rubber. In a week or two, its rupture will come out again, since the internal pressure of freon in the system is quite significant.

The air conditioner piping is rigidly fastened. It would seem that pipes and hoses (for example, an aluminum tube for car air conditioners) should last forever. Unfortunately, this is far from the case. There are several reasons for this:

piping adjacent to the outlet the collector cracks and burns out over time;
pollution and temperature drops;
the influence of road reagents;
significant fluctuations in humidity;
constant vibration from a running engine.

These and other factors have a damaging effect on aluminum tubes and rubber hoses. Therefore, sooner or later a moment comes when they do not withstand the load and become unusable.

Pipeline maintenance

car air conditioning will not cause difficulties even for a novice car enthusiast.

Cleanliness, periodic inspection is all you need to do to extend the life of your tubing and hoses by several years. The only thing that must be strictly observed is to use neutral materials when servicing. You can do this using water, a wooden scraper, and a hairbrush. The use of solvents and detergents is not advisable.

Repairing air conditioner pipes in a car is an inevitable problem that sooner or later every motorist faces. In the event of a crack or defect in the tube, freon will leave the system, which will lead to the failure of the car's air conditioner. Armed with the necessary tools, materials, patience and time, you can do the repairs yourself.

Many passenger car models are designed so that the piping to the A / C compressor runs next to the exhaust manifold. Due to the constantly high temperature, these elements gradually burn out, cracking and drying out.

The winter period is characterized by blockages in pipes and hoses, as a result of which the space between the radiator, cooling the engine, and the car air conditioning system is filled with dirt. In addition, factors such as the impact of road reagents, temperature changes, and an increase and decrease in humidity have a significant effect on aluminum tubes.

When repairing an automobile air conditioner, TIG welding is required in many cases, especially when it comes to large cracks.However, minor damage can be dealt with without using a welding machine. In this situation, special compounds are used, which are sprayed onto the surface in several layers. Thus, a kind of patch is obtained. It will take you only a few minutes to make it. Image - DIY repair of aluminum tubes of a car air conditioner

After applying the funds, it is necessary to put on a rubber tube of a larger diameter, which would completely cover the repaired part.

In many cases, making new parts for a car air conditioner will cost significantly less than buying them. If you decide to take such a step, it is very important to correctly measure the necessary parts and have the right tools. In order for the production to go smoothly, you must have a high-quality pipe cutter, pipe bender and several other tools in your arsenal. The pipe cutter will allow you to achieve high-quality cutting of the edges of the tube, and the pipe bender will make it possible to bend it at different angles without the risk of breakage.

An equally important point is the choice of the tubes themselves. Be careful - the manufacture of parts should be carried out in the measuring system, which is indicated in the vehicle registration certificate. Very often, drivers confuse inches for meters. To select suitable elements, it is necessary to measure the part on the fittings of the system, cut and, if necessary, bend in the right places, and also connect by welding.

Some cars are equipped with air conditioning systems, which cannot be repaired using the above method. Rescue hoses for car air conditioners made of rubber. This material, as you know, tends to crack and dry out, in addition, rubber in comparison with metal is much more susceptible to mechanical damage. Image - DIY repair of aluminum tubes of a car air conditioner

In case of minor damage to the rubber hose, you can also make a patch on it using special tools and compounds. However, in case of large defects, the hoses for the car air conditioners must be replaced with new ones, fortunately, their manufacture will cost you a small amount.

It is very important to carry out repairs related to the car's climate system on time, since otherwise malfunctions can lead to depressurization of the air conditioning compressor. And this, in turn, will cause clogging of the car's climate system with particles of compression rings, which can lead to more serious damage and financial costs for repairs.

Automotive air conditioning is one of the most significant and significant achievements of the modern automotive industry. The ability to cool the air inside the machine is worth a lot. The use of a car air conditioner is especially important for countries with hot climates, where high ambient temperatures persist throughout the year. Image - DIY repair of aluminum tubes of a car air conditioner

Heat has a depressing effect on the human body and negative factors tend to increase with age. The presence of an air conditioner in the car allows you to regulate the air temperature to optimal values. The air conditioner, like any air cooling unit, has its own system for distributing cooled air masses throughout the vehicle interior.

The elements of the transport system of freon gas, used to reduce the air temperature, are pipelines running in the engine compartment. Aluminum is used for the manufacture of pipelines. This is a rather "capricious" material with low resistance to temperature extremes and external factors. During long-term operation of the vehicle, it may become unusable in some areas.

Damage to the piping of the air conditioner leads to leakage of freon. It is a gas that cools the air circulating through the vehicle ventilation system. Freon leakage can lead to failure of the vehicle's air conditioning system.That is why it is very important to know how to repair the air conditioner tube with your own hands.

The pipeline for the vehicle air conditioning system is located in the engine compartment of the vehicle. In modern cars, even a finger cannot be pushed under the hood. All working elements of the engine and other systems are located very tightly. Unsurprisingly, there is a risk of damage to the air conditioner pipes when repairing the machine.

Often, the active operation of the vehicle leads to wear and tear of the elements of the air conditioning system. Despite the fact that the tubes are made of aluminum, it is quite easily damaged by careless handling of car service specialists or external factors (temperature drops, corrosion, friction and vibration).

Freon begins to escape through the cracks in the air conditioning pipes. It is a volatile gas that evaporates quickly. It is not possible to determine the leakage of freon visually or by smell.

The peculiarities of the country's climate suggest seasonal operation of the air conditioner. Active use of air cooling occurs only 4 or 5 months a year. The rest of the time the air conditioning system is idle. During the downtime of the air conditioner, the pipes of the system become contaminated with dust or dirt. All this negatively affects the efficiency of the system in the future.

Despite the appearance of a sufficient number of car service stations, garage repairs are popular among the majority of drivers. Some motorists spend the whole weekend on repairing their "iron horse". This is a real national hobby that combines passion and a real opportunity to save money.

In most vehicles, one push of a button is enough to activate the air conditioning and air cooling. If warm air flows continue to blow from the ventilation system, then the air conditioner compressor is not working. You need to look for the cause of the malfunction.

If you have any concerns about the performance of the air conditioning system, do not hesitate. Early diagnosis makes it possible to quickly identify malfunctions and take measures to eliminate them.

Connecting special equipment for diagnosing the machine's air conditioning system allows you to determine the location of the freon leak. It is very convenient and saves a lot of free time for the car enthusiast.

Detecting a refrigerant gas leak allows the vehicle owner to take other actions to repair the air conditioning system.

Small cracks on the surface of the air conditioning system pipes are easier and faster to repair using special repair compounds. As a rule, they are realized in aerosol form and applied to the damaged site through spraying. It does not take much time to solidify the working substance of the repair composition. After 12 hours, the conditioner can already be used.

The presence of a welding machine, despite its availability, is not common. You need to know how to use the device correctly, otherwise the repair efficiency will tend to zero. If the piping of the air conditioning system resembles a sieve, it is best and more profitable to use welding.

If the car is early years of release, pipelines have to be repaired often. Often not a month goes by without repair work. In this case, it is easier to replace the air conditioner pipeline than to try to "patch" it. It will be cheaper and more efficient.

Aluminum or rubber air conditioning lines can be purchased for almost all vehicle models. The difference lies in the cost and complexity of the installation. Rubber piping is more affordable and easier to install.

The choice of means for repairing the piping of the air conditioning system is wide and varied.That is why it is difficult to make the right choice and purchase an effective remedy. The savings will have a negative effect on the repair effect, since it will be short-lived.

The following tools, which are popular among motorists, can be distinguished for repairing car air conditioner pipes:

1. Mannol Epoxidkitt Stahl + Metall.

A special repair compound for restoring the surface of air conditioner tubes. Convenient for quick DIY repairs. All damage is effectively filled. Suitable for the repair of metal elements. Complete hardening of the composition occurs in 15-20 minutes, depending on the ambient temperature.

2.MANNOL EPOXY-METAL (30 gr.).

Special repair compound based on epoxy resin. Provides fast adhesion of damage on the surface of the air conditioner piping. Complete hardening of the product occurs within 5 minutes.

3. Self-sealing rubber tape Mannol MULTI-TAPE 5M.

Insulates and protects the elements of the air conditioner piping from corrosion. The tape is resistant to mechanical stress, temperature extremes and aggressive media. An easy-to-use and effective tool for repairing air conditioning systems.

If desired, and a small area of damage to the air conditioner pipelines, all repair work can be performed independently without outside help. Actions will help restore the functionality of the vehicle's interior cooling system.

During the operation of the air conditioner, various troubles occur. The most common problem is tubing repair.

When the air conditioner is used in cooling mode, when the air temperature is below zero, an ice plug may form in the drain pipe, blocking the condensate drain hole. The main consequence of this circumstance will be leakage from the indoor unit. In this case, no repairs are required. You just need to wait until it gets warmer on the street, and the cork will melt by itself.

More serious problems are caused by damage to the refrigerant pipes of the air conditioner, arising from the following reasons:

violation of the integrity of the tube surface due to mechanical damage;
chafing of the inner tubes due to strong vibration during intensive operation of the compressor or fan;
deformation or destruction of the tube walls under the influence of the environment (UV radiation, wind, precipitation and other factors).

The split system is designed in such a way that the most vulnerable area is the trunk connecting its main modules. As soon as there is a suspicion of a refrigerant leak, the first step is to visually inspect the freon track. It usually consists of tubes that should not react with freon and oil. In this case, it is necessary that they are protected from corrosion.

Copper is the best suited for such purposes. When interacting with the chlorine contained in freon, copper is oxidized and covered with a protective layer that prevents the appearance of rust.

It works through the use of human muscle strength, has several types of semicircular nozzles.

Special tools are not always at hand, so another method can be used to bend the tube. For example, using a spring.

First you need to choose a spring. If the tube diameter is large, then a smaller diameter spring is used, which is pushed into the inside of the tube. For a thin tube, you can take a large spring and put it on top.

2. Then heat the tube with a gas torch or blowtorch.

3. When the metal darkens, bending can begin.

4. Leave the workpiece to cool completely.

Aluminum tube is also widely used in the installation of air conditioners and for supplying refrigerant, as it has a number of advantages over copper:

low price;
better flexibility;
quick and easy soldering, saving effort and time, as well as the consumption of solders and gas;
low heat content;
higher corrosion resistance;
the softness allows you to spend less effort on flaring.

The properties of aluminum are such that its surface is rapidly oxidized under the influence of oxygen and a protective oxide film appears on it. This film interferes with the sealing of aluminum tubes.

Therefore, the question often arises: how to solder the aluminum tube of the air conditioner? If such a need arises, it is recommended to use fluxes and solders. With them, the seams are smooth and durable.

To solder aluminum parts you will need:

gas cylinder;
solder for brazing aluminum (for example, Castolin 192 FBK);
gas burner or blowtorch.

back to contents ↑

Cleaning the surface from oxide film and dirt. This is done in two ways: mechanical (using a grinder, sandpaper, metal mesh or brush) or chemical (using chemicals - fluxes).

Exposing parts in the desired position relative to each other.
Application of flux to the joint.
Heating the solder tube with a blowtorch or gas torch.

Solder application. In this case, overheating should be avoided, as a result of which the parts to be joined may melt. It is necessary to control the heating process to the operating temperature by constantly applying solder. When its tip begins to melt, then the temperature is optimal.

If no flux is used, then a striking motion should be made with the tip of the solder. This measure will help get rid of the oxide film and make the seam more durable.

Soldering helps to solve the problems of repairing worn-out parts, violation of the tightness of pipes, without resorting to expensive assistance of qualified specialists.

How to quickly repair an auto air conditioner tube with your own hands? Before buying a long-awaited car, the buyer makes more and more demands on it. Simple audio preparation, increased ground clearance, and other things are no longer enough. The future owner wants to have increased noise and heat insulation, sufficient ventilation, optimal temperature.

Therefore, the car must be equipped with at least a cruise and climate control to ensure ease and comfort of movement. For more demanding buyers, heated steering wheel and front seats, rear disc brakes, front and side airbags.

Many automakers, in order to attract more and more customers, try to fit the maximum possible number of options into the budget cost of the car.

The Japanese and Koreans are especially generous in this regard, who often equip the interior of a car of an average cost with the "Lux" package. It may not always be profitable from an economic point of view for the concern, but in conditions of tough competition, you always have to sacrifice something, sometimes profit, in order to increase demand.

How to quickly spend DIY auto air conditioner tube repair lacking skills and experience? First, you need to carry out visual diagnostics and make sure that the unit is inoperable. If, when you press the power button for the climate system, nothing happens and the indicator on the center panel does not light up, then there is a freon leak.

You should quickly open the hood and look at the piping of the air conditioner. Clear visible oily spots will directly indicate cracks in the pipes and gas leaks. As a result, the compressor will automatically shut down for safety and overheating protection. After 100% confidence in the cause of the breakdown, we proceed to eliminate it.

It should be noted right away that the reason for the appearance of cracks in pipelines can be:

Factory defect of the product;
The consequence of strong and frequent vibrations in the power unit. This is possible if the rubber cushions on which the motor is attached break off;
Close proximity to exhaust manifold. Typical for old-style foreign cars;
Dirt clogging and temperature fluctuations that negatively affect the aluminum pipes.
We drive into an inspection pit or overpass, turn off the engine, squeeze out the handbrake, turn on the first speed for safety;
We inspect the integrity of the mounting cushions from below. In different modifications, there can be 2 or 3. As soon as we see a break, the rubber seal should be changed immediately. Otherwise, replacing the pipelines will not help us for a long time, the cracks will go back to the first hundred kilometers;

If there are no defects in the pillow, then we proceed to replace the hoses;

After reviewing the entire conditioning chain, we select the critical areas for replacement. Next, we inspect the radiator and aluminum tubes for integrity and cleanliness. If necessary, blow through with compressed air and clean;

Unscrew the flanges with an open-end wrench to "14" for foreign cars or to "17" for domestic cars with a branch pipe and replace them with new ones. Be extremely careful, as the remnants of freon can be sprayed on the face;

All that remains is to pump gas into the system and check its performance;

It is possible to pump refrigerant into the air conditioner and its branch pipes only with the help of a special compressor. If one is not available, then you will have to seek help from a service station for gas injection;

If there is, then we connect two pipes to the supply and return on the compressor, start the unit itself and fill the system with R-113, R-11 refrigerant in accordance with the required amount. The norms for each car are different. Specific data can be found in the operating instructions in the section refueling capacities;

We start the engine, turn on the compressor, set the required temperature in the cabin. We carry out visual diagnostics of the branch pipes for the presence of freon leakage.

Sometimes it happens that the honeycomb of the air conditioner radiator is damaged. Actually, there are two ways out: if you have money - buy a similar new one, if not - fix it using argon-arc welding with spraying. Before carrying out work, you should download the refrigerant from the system, dismantle the radiator itself, use a burner to seal the defective place, install and test for operability. The main reason for the failure of the radiator is the negative impact of the environment and corrosion.

In conclusion, consideration of the topic, do-it-yourself auto air conditioner tube repair, I would like to note that the average service life of the climate system is from 5 to 7 years. Depending on how the owner conducts preventive maintenance and operates the air conditioner, its duration of continuous operation depends.

Repair of air conditioner pipes is a very significant part of repair and restoration work on car air conditioners. Defects in the pipes lead to freon leaks, and, as a result, the appearance of frost on the outdoor units, incorrect operation of the air conditioner. There are many reasons for the depressurization of the tubes: corrosion, mechanical stress, wear of the tube joints. And the tubes have a very small diameter and wall thickness, which does not allow the use of welding when repairing air conditioner tubes, and it is also necessary to ensure tightness. DIMET technology allows delicate repair of air conditioner tubes without exposing the parts to heat, ensuring excellent tightness of the joints.

Consider the repair of air conditioner tubes by spraying using examples:

Through defects were found in a simple tube, on the street +35. Several areas of corrosion damage are visible.

Powder the surface of the tube to better identify deep corrosion spots and holes.It is obvious that a full-fledged repair with DIMET is needed.

Spray metal tubercles on the marked defects, and go over the defects in the rest of the tube.

We cut off the excess bumps, the tube is smooth. We will ensure reliability by applying a thin layer of metal to the treated part.

Spraying a thin layer, we found more points of corrosion, there are much less of them, but we will process them too. We will not level the layer - reliability is already with a margin, and the beauty of the coating is not important here.

Review of the company "Mercury Motors" on the repair of aluminum tubes of air conditioners DIMET:

Corrosion has eaten away a section of the A / C tube. The joint of the two parts is still holding on to the remains of the tube wall, but we will carry out repairs.

Gently squeeze the joint, spray the composition A-20-11 in the “4” mode. We cut off the extra bumps with a file, and finally seal in the “2” mode. The tube is now airtight, but the coating material is fragile and it is necessary to strengthen the weak joint.
