The characteristics of rubber hose are physiological inertness, UV resistance, ozone resistance, high and low temperature resistance (-80 to 300 degrees), high transparency, strong resilience, compression and permanent deformation, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, Flame resistance, voltage resistance, conductivity and other properties.

It is mainly connected to the engine and air filter, engine and radiator system, automobile air-conditioning system, etc. As a component of the air intake system, it is closer to the engine, so it needs high temperature resistance, oil resistance, corrosion resistance, aging resistance, low temperature resistance, etc. Its materials are of many types depending on the processing technology. Vacuum brake pipe, good oil resistance, high rubber content, but relatively poor ozone resistance; EPDM is used in automotive water pipe series. Such as radiator hoses, air conditioning pipes, etc. There are also some high-performance materials, such as AEM acrylate resistant to high temperatures and so on. Each rubber has its own characteristics, so it is particularly important in the choice of hose material. NBR is not suitable for fuel systems. Therefore, the substituted NBR+PVC rubber and FKM rubber hose is relatively extensive.
