The cost of automobile oil pipe rubber parts is about 10% of the cost of automobiles. Except for most of the tires, other rubber products are small pieces, which are also installed in the engine, fuel tank and other important parts to ensure the normal operation of the car. Let's take a look at what hoses are commonly used in automobiles:

Automobile air conditioning tube.

In the hot summer and cold winter, the truck will inevitably turn on the air conditioner to make the interior. At this time, the role of the air conditioning tube is reflected. The inner rubber layer of automotive air conditioning hose is made of EPDM rubber. It has high and low temperature resistance and air tightness. Whether it is cold wind in summer or hot wind in winter, we can meet our needs. Car cooling water pipe.

Cooling water pipes are mainly used for cooling systems of automobiles. The main function of the automotive cooling system is to dissipate part of the heat absorbed by the heating components in time to ensure that the best temperature is maintained, so that the engine and other components can work normally, and because the current domestic operating temperature is that the cooling water pipe can reach 120 degrees Celsius. Therefore, the inner and outer layers of the cooling water pipe are made of vulcanized EPDM rubber.

Car return pipe.
Nowadays, most EFI vehicles have return pipes. When the fuel pump is supplied to the engine, the fuel pump will supply more oil to make the engine fully run. In order to reduce gasoline pressure and reduce fuel consumption, gasoline will eventually flow. Return to the fuel tank, this process is completed through the return pipe of the car. Although he is an obscure part of the engine, it plays a very important role in the normal operation of the engine. For pneumatic braking systems, please note that the system drains frequently and regularly replaces the dryer. Moisture in the pneumatic system will corrode the pipeline and affect the braking effect. In severe cases, it may even cause the brake system to malfunction. In addition, be sure to check the operation of the pump and the wear of the pump belt. If problems are found, they should be replaced in time.
