Types of automotive rubbers and seals
O-Ring
O-rings are a common type of seal, usually made of rubber or other elastic materials. They have an annular cross-section that creates a tight and reliable seal between two mating surfaces, preventing leakage of liquids or gases. In automobiles, O-rings are widely used in engines, transmissions, hydraulic systems and other parts.
Seal Strip
Seal strips are long rubber products used to fill and seal gaps in automotive structures. They are usually used in doors, windows, luggage compartments, etc. to ensure that the interior of the vehicle is not affected by outside water, wind, noise, etc.
Rubber Hose
Rubber hose is a connecting part of a pipe used to transmit liquids or gases. In automobiles, rubber hoses are usually used in the cooling system, fuel system, exhaust system, etc. and are subject to high temperature and pressure requirements.
Rubber Gasket
Rubber gaskets are round or square seals used to fill and seal the gap between two mating surfaces. They are commonly used in the connecting parts of automobile engines and transmission systems to ensure sealing and prevent liquid or gas leakage.
Functions of automotive rubbers and seals
Sealing Function
The main function of automotive rubbers and seals is to provide a seal that prevents liquids, gases or dust from entering or escaping from the automotive system. They ensure a tight connection between components to keep the system functioning properly.
Vibration damping and sound insulation function
Rubber seals have a certain degree of elasticity and vibration damping ability, which can reduce the vibration and noise of the car during driving, and provide a more comfortable driving experience.
Chemical corrosion resistance
Automotive rubbers and seals need to be able to resist the corrosion and erosion of various chemicals used in the automotive system to ensure its long-term stable performance.
High and Low Temperature Resistance
Due to the temperature changes during the operation of the car, rubber and seals need to have a high resistance to high and low temperatures in order to maintain their reliable sealing and elasticity.
Application of automotive rubbers and seals in automotive systems
Engine system
Rubber seals are used in engine cylinder heads, crankcases, cylinder gaskets and other parts to ensure the sealing of the combustion chamber and prevent water and oil leakage.
Brake system
The main role of rubbers seals in the braking system is to ensure the stability of the brake fluid and prevent system leakage, so as to ensure the reliability and safety of the brake.
Cooling System
Rubber hoses and seals play the role of connection and sealing in the cooling system to ensure the flow of coolant and the normal operation of the system.
Fuel system
Rubber seals are used in fuel pumps, injectors, fuel tanks and other parts to prevent fuel leakage and ensure the safe and efficient operation of the fuel system.
Air conditioning system
O-rings and rubber seals are used in automobile air-conditioning system to connect and seal compressor, condenser, evaporator and other parts to prevent refrigerant leakage and ensure the cooling effect of air-conditioning system.
Suspension system
Rubber seals in the suspension system play a role in damping and sound insulation, providing a smoother ride and driving experience.
Summary
Automotive rubbers and seals are indispensable components of the automotive system, they provide sealing, vibration damping, sound insulation and chemical corrosion resistance, etc., to ensure the normal operation of the automotive system and the safety and comfort of the driver.
Different rubbers and seals are suitable for different parts of the automotive system, so the right materials and specifications should be selected to ensure their quality and performance meet the requirements when repairing and replacing them. For non-professionals, it is recommended to seek the help of professional technicians when handling automotive rubber and seals to ensure proper operation and safety.
