O-Ring with a FEP PTFE outer layer encapsulating a Solid FKM core. The PTFE shell offers excellent chemical and temperature resistance while the FKM core provides the resiliency needed to provide effective sealing. The FKM core provides improved chemical and compression set resistance resulting in longer sealing life in some applications. Less compressible than Silicone which can result in leaking issues in some applications.

4. The advantage of FEP encapsulated O-Rings
Exceptional protection against aggressive chemicals and gases.
Cost effective alternative to FFKM O-Rings.
Low coefficient of friction and therefore less wear.
Elastomer core ensures that the O-ring can set properly.
No permanent pressure deformation that can occur with solid PTFE O-rings.
