FEP Encapsulated O-Ring

FEP Encapsulated O-Rings combine the excellent chemical resistance of Fluorinated Ethylene Propylene (FEP) with the elasticity of an internal elastomer core. This dual-structure design provides reliable sealing in environments where standard rubber O-rings cannot perform.

1. Standard FEP Encapsulated O-Ring

2. Seamless Encapsulated O-Ring

3. Custom Profile Encapsulated Seals
