【FEP O-ring 】

TOP-SEALING FEP O-ring 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.

Applications:
It can be used wherever an elastomer’s chemical resistance is insufficient. Here FEP and PFA materials offer chemical resistance while the elastomer core provides elasticity. Seals made of PTFE are not an option in this case. The material does offer outstanding media resistance, but is not associated with elasticity.

Advantages:

1. Excellent chemical resistance to a wide range of fluid media.

2. High level of hugiene for use with foodstuffs and edible oils.

3. Far better elasticity and seal ability than solid PTFE rings.

4. Operational temperature ranfe of -60℃ to +200℃.
