The Soft-Seal is a valuable option for systems that handle easy-crystallizing or particle-contaminable fluids. Small elastic parts, which are as chemically inert as Teflon™, protect sealing surfaces from particles in the liquids, reducing common leakage problems with Teflon™ valves.

Perfluoroelastomer, the elastomer used for the Soft-Seal, has a stable molecular structure consisting of only fluorine, carbon, and oxygen atoms. Outstanding resistance to almost all chemicals. We have a Chemical Compatibility Table, which has more details.
