FPM Material Rubber oilseal
An oil seal, also known as a shaft seal, is a device part used in a machine to prevent fluid (mostly lubricating oil) from overflowing from a joint (mostly the joint surface or the shaft of a part). Static seals and dynamic seals (usually reciprocating) are called seals. The representative form of oil seal is TC oil seal, which is a double-lip oil seal with self-tightening spring completely covered by rubber. Generally speaking, oil seal often refers to this tc skeleton oil seal.

Skived PTFE sheet is manufactured by technology of compacting, sintering, rotary cutting with PTFE granular resin. As PTFE has a very low co-efficient of friction, so the surface of skived teflon PTFE sheet has similar friction levels to ice. Skived teflon PTFE sheet can work at -180° C ~+260° C and is the best electrical insulator of all known plastics.Skived Sheet0.00Skived PTFE sheet is manufactured by technology of compacting, sintering, rotary cutting with PTFE granular resin.
