Product Overview
Description
oring
Covered O-ring introduction The UPC wrap seal organically combines the elasticity and sealing performance of rubber with the
chemical resistance of PTFE. It is composed of a silicone or fluorine rubber inner core and a relatively thin FEP or PFA outer
covering. Universal Seal has excellent sealing performance. Rubber O-rings are easy to wear, have poor chemical resistance and gas
permeability resistance, and pure PTFE O-rings have high hardness and can resist compression but have poor elasticity. Covered
FEP/PFA O-rings have good swelling resistance and chemical stability (unless attacked by alkali metals, fluorine and some halides
at high temperatures) and have good elasticity near the rubber O-rings, FEP The friction coefficient of /PFA is very small (only
0.1~0.2), and it has excellent resistance to gas permeation. These properties make U-PFA seals truly applicable in harsh
environments.
