Hydraulic rubber hoses used for automobiles

Released on Oct. 10, 2022

With the continuous development and progress of society, automobiles have become more and more important means of transportation in people's lives. As an important part of automobiles, hoses are responsible for transporting oil, gas and water in automobile systems.

The pipes used in automobiles mainly include fuel pipes, brake pipes, air conditioning pipes, power steering pipes and radiator pipes. Next, the functions and usage requirements of the pipes required by each part are introduced from the following parts:

1. Fuel pipes

The fuel pipe in automotive applications mainly connects the fuel tank and the engine. The high pressure fuel pipe of the automobile transmits the fuel to the engine of the automobile to generate power; on the other hand, it is also used to transmit the evaporated oil and gas to the fuel purification system and to transport the fuel exhaust gas. These applications require that the fuel rubber hose must have the characteristics of fuel resistance, high temperature resistance, blast resistance and high pressure resistance. Automobile fuel pipes are generally composed of three layers: inner rubber pipe, reinforcement layer and outer rubber layer.

2. Brake pipes

The automobile brake pipe is an indispensable part of the automobile system and cannot be replaced. It mainly transmits the braking force to the brake caliper to ensure the successful operation. The previous automobile brake hoses were generally made of styrene-butadiene rubber (SBR) as raw materials. Later, with the continuous improvement of performance and energy-saving requirements, the materials of brake hoses also become diverse: EPDM rubber, nitrile butadiene rubber (NBR) and neoprene have been obtained. more applications.

3. Air conditioning pipes

Automobile air-conditioning hoses are used in the refrigeration system of automobile air-conditioning to transmit gaseous or liquid refrigerants of various pressures to achieve refrigeration effects. Automobile air-conditioning hoses need to have the characteristics of high pressure resistance, low penetration and high temperature resistance, and can be used normally under the temperature of -40℃~+160℃. Generally, the inner rubber layer of automobile air conditioning hose will be made of EPDM and neoprene.

4. Power Steering pipes

The power steering hose is used to transport the steering mineral oil that reduces the steering resistance. This part of the hose is required to have good oil resistance, wear resistance and high temperature resistance. Generally, hydrogenated nitrile butadiene rubber and neoprene rubber are used as the inner rubber layer.

5. Radiator pipes

The cooling system is a key part of the car. The main function is to exhaust the heat of the heated parts in time to ensure the normal operation of the car at a suitable temperature. With the double high requirements of energy saving and performance of the car, the requirements for the hose used in the radiator are also higher. the hose must withstand extremely high and low temperature conditions. The rubber hose of the automobile cooling system is generally made of EPDM rubber.

The above are the systems that require hoses in automotive applications and the functional characteristics of the required hoses. We provide high-quality hoses for automotive applications. You can contact us to recommend suitable products for you.
