Rubber air conditioning hose is widely used in air-conditioning systems of various vehicles (cars, machinery, trains, trams) as well as in smaller installations of industrial cooling. In these installations, freonmixed with compressor oil acts as a refrigerant. It circulates in the system where it undergoes continuous pressure and temperature fluctuations. Therefore, requirements air-conditioning hoses are so high. It is essential for the air-conditioning hoses to be perfectly tight as freon is very penetrating, expensive and harmful to the environment. The hose must be highly resistant to pressure, temperature, chemicals and stop humidity from permeating the hose wall. It’s a great auto hose.
