FEP PFA Encapsulated O Ring Seal Oil Resistant O Rings High Sealing Performance
FEP/PFA fep encapsulated o-ring, PTFE/FEP/PFA Encapsulated O Rings, PTFE FEP encapsulated FKM FPM o
PTFE Encapsulated O Ring
1.PTFE FEP/PFA encapsulated O Ring are designed to combine the sealing properties of the rubber O Ring with the chemical resistance of PTFE.
2.They are generally manufactured rubber or silicone rubber and are coated in a thin molded layer of FEP or PFA.
3.This provides a unique seal popular for high friction and aggressive chemical applications. FEP encapsulated O-Rings are our most common and are resistant to solvents and chemicals.
4.They have a low coefficient of friction and a very low permeability to gases making them suitable for harsh environments.
5.PTFE Encapsulated O Ring also have a good elastomeric memory.
Product Description

| Advantage |
high temperature for punching machine seals are designed for the most hostile chemical and temperature environments. It combines the best qualities of two materials, FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience. This unique combination forms a highly effective, long lasting seal for the most demanding applications.s
