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

A seamless FEP or PFA jacket gives the seal chemical inertness, whilst the elastomer core gives the seal resilience and energises the seal 다운로드. Only the highest quality materials are used to make our Encapsulated seals.

Jacket Contruction

We offer a choice between two jacket materials: FEP (our standard) and PFA for more demanding applications 다운로드.

Our Encapsulated seal jackets are made with
Teflon® FEP or PFA 레포데2.

Core Materials

The energising core is available in Viton®, Silicone or EPDM 다운로드. Viton® is offered as the standard because of its superior compression set 다운로드. For low-temperature applications, or where lower closure forces are required either a solid Silicone or hollow Silicone core is specified.

Our standard Viton® core has an incredible Compression set of  only 4.6%

… and our Silicone core only 9.2%

Design Variations

We can offer other non-standard core materials such as: FDA Metal detectable or USP Class VI – please contact our sales office for more details 레나 마리아.

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 다운로드.

The standard available styles of Enacapsulated seal are O-rings, Cam and groove gaskets and Milk coupling gaskets to DIN 11851 영화 화산고 다운로드.
