The hoses used in automobiles mainly include fuel hoses, air conditioning hoses, brake hoses, radiator hoses, turbo booster hoses, power steering hoses, exhaust pipes and air intake hoses.

Automotive rubber hose structure and function

The structure of automobile rubber hose is mainly composed of three layers:
Inner layer: made of oil-resistant, abrasion-resistant, high-temperature-resistant rubber material, responsible for direct contact with the medium to ensure the smooth delivery of the medium.
Middle layer: usually composed of cord fabric layer or steel wire braid layer, which plays a role in enhancing the strength of the hose body and preventing bursting.
Outer layer: made of rubber or plastic material, protects the inner layer and the middle layer from external environmental erosion and prolongs the service life.

Types of automotive rubber hose

Cooling system rubber hose: used for the flow of coolant, connecting the engine, radiator and water pump.
Fuel system rubber hose: responsible for transferring fuel to the engine, with oil resistance and high temperature resistance.
Hydraulic System Rubber Hose: Used for transferring hydraulic fluid, commonly found in braking and steering systems.
Rubber hose for air conditioning system: connects the compressor, condenser and evaporator to ensure the normal operation of the air conditioning system.

Characteristics of automotive rubber hose

High temperature resistance: able to work for a long time under the high temperature environment of the engine, not easy to deform or aging.
Corrosion resistance: able to resist the erosion of fuel, coolant and other chemicals, maintain stability.
Good elasticity: good flexibility and resilience, adapt to the complex working environment of the car.
Excellent sealing: can effectively prevent fluid leakage and ensure the normal operation of the system.

Application of automotive rubber hose

Engine cooling system: through the cooling system rubber hose, the coolant circulates when the engine is running, effectively reducing the engine temperature.
Fuel delivery system: the fuel system rubber hose is responsible for fuel delivery from the fuel tank to the engine to ensure adequate fuel supply.
Brake system: The hydraulic system rubber hose serves as the transmission channel for brake fluid, ensuring the sensitivity and reliability of the brake system.
Air conditioning system: The rubber hose of air conditioning system connects all key components to ensure the flow and circulation of refrigerant and keep the car comfortable.



    Automotive rubber hose, although it seems inconspicuous, but carries a vital mission. Choose high-quality products, careful maintenance, in order to extend its service life.
