Due to the different requirements of the environment and the conditions of the occasion, the small series tells you that the medium of the rubber seal material used in the oil seal is different, which also determines the environment and occasion of the use and application of the oil seal developed and produced.

Polytetrafluoroethylene has chemical stability, has a good chemical inertia, strong acid and alkali or strong fluorinating agents and organic solvents are not effective; Good thermal stability, the surface of the material has outstanding surface self-lubrication, almost viscous substances can not adhere to its surface; Allows normal use in high-speed situations and environments.

Ptfe oil seals are widely used in the field of weapons industry, aviation industry, hydraulic and pneumatic systems, oil tubing, reciprocating and rotating shaft oil seals in the petroleum industry, and the combination of rubber elastomer to make composite oil seals.
