PFA Encapsulated O Ring

PFA Encapsulated O Ring
Product Introduction:
SUNPASS FEP-/PFA-encapsulated O-rings consist of an elastomer core and a seamlessly closed casing of modified PTFE. The elastomer core made of FKM (Viton) or VMQ (silicone) guarantees an even pretensioning at the sealing point. The seamless casing is composed of FEP (fluorinated ethylene propylene) or PFA (perfluoroalkoxy-copolymer). It ensures reliable sealing and high resistance to aggressive media. This produces performance similar to that of a PTFE material. Encapsulated O-rings are exclusively used in static applications since movement or abrasive media can destroy the casing. Aggressive chemicals or extreme temperatures can destroy conventional O-rings and will ultimately leads to leakage.
