FEP Encapsulated FKM/FPM O-Ring

FEP encapsulated O-rings comprise of an elastomer core which has been seamlessly encapsulated in a jacket of ® fluoropolymer. The core is either Viton ®, Silicone or EPDM. The jacket is FEP or PFA.

FEP encapsulated O-rings are recommended when a standard O-ring has inadequate chemical resistance for an application. They are also recommended when a solid PTFE O-ring does not have the elasticity for reliable, long term fluid sealing. They are often used where chemical resistance and or hygiene is required.

Typical industries include:
• Chemical.
• Petrochemical.
• Food.
• Pharmaceutical.

Application:

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 ® with the resilience of rubber.

A seamless ® 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 ® jacket – FEP which is standard, and PFA for more demanding applications.

The energising core is available in Viton®, Silicone or EPDM.

Viton® 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.
