- PTFE, or Polytetrafluoroethylene, is a highly versatile synthetic polymer renowned for its exceptional chemical resistance, low friction coefficient, and high-temperature stability. It finds extensive application in various industries, particularly in the manufacturing of oil seals. An oil seal, fundamentally, is a mechanical device designed to prevent the leakage of oil while allowing the rotation or linear movement of shafts and axles. The integration of PTFE into oil seals brings about a myriad of advantages.
(4) The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a W-shaped oil seal can be used.
A synthetic rubber used in gaskets, o rings, lip seals, and other moulded devices, Viton offers sealing properties for a range of oil-based applications. Viton with high fluorine grades will also produce excellent resistance to swell, especially in oxygenated fuel and high-octane blends.

By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
