Find the right pressure hose with car model

How do I know if my pressure line is leaking?

There are several ways to check if there's a leak in the pressure line:

Visual inspection: check the pressure line for leaks around the connections, joints, and along the length of the pipe.

Use leak detection fluid: there are special leak detection fluids that you add to the system. These often contain a dye. You add the fluid to the air conditioning system and switch on the air conditioning. If there's a leak, you'll see the fluid coming out. Small leaks can be solved with special sealants that you inject into the system.

Pressure test at the garage: During a pressure test, the air conditioning system is connected to a compressor and pressurised. If the compressor cannot maintain the pressure, this indicates a leak. A detection fluid is often used to pinpoint the exact location.

Buying a pressure line

If your pressure line is leaking, you can easily order a new one. The fit of the line is very important. You can find the correct line for your car. The air conditioning system is under pressure and should only be serviced by a mechanic with the correct materials and knowledge. You can keep costs down by supplying the correct part yourself and thus save on material costs.

Besides pressure lines, you can find many other parts for your air conditioning system.

A/C high pressure hose

If the car's pressure hose is leaking, the air conditioning will no longer function properly. The air conditioning pressure line carries refrigerant throughout the system. This refrigerant provides the cooling effect. It exists as both a gas and a liquid within the air conditioning system and can therefore escape through even a small leak. In addition to your air conditioning no longer getting cold, using a leaking air conditioning system can lead to overheating and damage to the system. At Winparts, you can order a new pressure line for various car makes and models quickly and easily.
