NNK Common Oil Seal Materials

31 Jul.,2025

NNK Common Oil Seal Materials.Oil seal is a mechanical seal used to seal liquid or gas, usually used to prevent the leakage of lubricating oil, liquid or gas, especially at the contact between the rotating shaft and the housing. The material and design of the oil seal directly affect its performance and service life.

 

NNK Common Oil Seal Materials

Common oil seal materials

1.Fluororubber (FKM)

Features: Excellent high temperature resistance, oil resistance, and corrosion resistance, suitable for harsh environments, such as high temperature and chemical corrosion environments.

Application: Suitable for automotive, aviation, chemical and other fields, especially for sealing of oil, fuel and chemical liquids.

2.Nitrile rubber (NBR)

Features: Oil-resistant, grease-resistant, and wear-resistant, suitable for conventional working environments. Its temperature resistance range is usually -30℃ to +100℃, and its tolerance to water and certain chemicals is weak.

Application: Widely used in oil seals in the automotive, machinery, home appliances, petroleum and other industries.

3.Polyurethane (PU)

Features: Good wear resistance and mechanical properties, good elasticity, suitable for high-load and high-speed applications, and good oil resistance and low temperature resistance.

Application: Suitable for high-load industrial equipment sealing, especially widely used in hydraulic systems.

4.Silicone rubber (SI)

Features: Excellent high temperature resistance and can work at extreme temperatures. Silicone oil seals have good electrical insulation and physiological safety.

Application: used for sealing applications in food, medicine and other industries.

5.Polytetrafluoroethylene (PTFE)

Features: corrosion resistance, high temperature resistance and low friction coefficient, suitable for environments requiring extremely high sealing performance.

Application: suitable for chemical equipment, high temperature equipment, petrochemical and other fields.
