FEP Encapsulated O-Ring

FEP-encapsulated O-rings have a core of elastomer that is completely covered with a seamless sheath of FEP fluoropolymer. The elastomeric core is normally either fluorocarbon (FKM) or silicone (VMQ).

An Encapsulated O-Ring is Recommended When:

• A standard elastomeric O-ring has inadequate chemical resistance for a specific application
• A solid PTFE O-ring does not offer sufficient elasticity for reliable, long-term fluid sealing
