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.
