Product Description
Automobile O-rings are usually made of different kinds of materials, and the specific choice of materials depends on their application environment and requirements in automobile systems. Common automotive O-ring materials include:
1. Fluorocarbon (FKM/Viton): Fluorocarbon has excellent oil resistance, high temperature resistance and chemical corrosion resistance, and is suitable for working environments with high temperature, high pressure and strong chemical corrosion, such as engine seals and fuel systems.
2. Ding Qing rubber (NBR/Nitrile): Ding Qing rubber has good oil resistance and wear resistance, and is suitable for sealing parts such as general hydraulic system, air conditioning system and braking system.
3. Silicone rubber (VMQ/Silicone): Silicone rubber has excellent high temperature resistance and aging resistance, and is suitable for sealing in high temperature environment, such as engine cooling system and turbocharger system.
4. Propylene rubber (ACM): Propylene rubber has good heat resistance and oil resistance, and is suitable for high temperature and high pressure environments such as engine seals and gearbox seals.
5. CR/Neoprene: CR has good oil resistance and aging resistance, and is suitable for sealing under general working conditions, such as air conditioning systems and braking systems.
In addition to the common materials listed above, other special materials, such as polytetrafluoroethylene (PTFE) and polyetheretherketone (PEEK), can be used for automobile O-rings according to the specific use requirements and environmental conditions. Choosing suitable materials can ensure that O-rings have good sealing performance and durability in automobile systems.
