Encapsulated seals were primarily designed to solve the growing problems of sealing corrosive fluids in industry. This development provided designers and engineers with a seal that combined the chemical resistance of PTFE with the resilience of rubber.

A seamless PTFE jacket surrounds the elastomer core providing the chemical inertness, whilst  the memory in the elastomer core energises the seal.

Encapsulated seals are available with two types of PTFE jacket - FEP which is standard, and PFA for more demanding applications.

The energising core is available in FKM, Silicone or EPDM.

FKM is offered as the standard because of its superior compression set.  For low-temperature applications, or where lower closure forces are required a Silicone core is specified.
The design variations available, together with combined performance characteristics of both the jacket material and elastomer core , ensures that encapsulated seals will be an effective solution for many troublesome applications.
