FEP / Viton Encapsulated O-rings

Overview

FKM (Viton) fluoroelastomer core encapsulated in seamless FEP. Combines Viton's chemical and heat resistance with the inert, non-stick surface of FEP. Higher chemical compatibility than silicone-cored variants for hydrocarbons and aggressive process fluids. Identifiable by the black core at the seam.

Typical Applications

• Aggressive hydrocarbons, fuels, oils and acids
• Higher pressure and dynamic applications than silicone-core
• Chemical processing equipment
• Pump and valve seals where Viton properties are needed plus FEP non-stick surface
• Static and dynamic sealing in rugged industrial environments
