Product Introduction

FEP Encapsulated Silicone O-Rings

Encapsulated O ring with a FEP or PFA (Teflon®) outer layer encapsulating a Silicone core. The Teflon® shell offers excellent chemical and temperature resistance while the Silicone core provides the resiliency needed to provide effective sealing. Readily available in common USA and metric cross-sections and nearly unlimited diameters. FEP encapsulated Solid Silicone with improved chemical resistance up to +200℃ PFA encapsulated Solid Silicone up to +260℃.


FEP Encapsulated FKM (Viton ® ) Core

Encapsulated O ring with a FEP (Teflon®) outer layer encapsulating a Solid FKM (Viton®) core. The Teflon® shell offers excellent chemical and temperature resistance while the FKM core provides the resiliency needed to provide effective sealing. The FKM core provides increased chemicals and compression set resistance resulting in longer lasting sealing in some applications. Readily available in common USA and metric cross-sections and nearly unlimited diameters. FEP encapsulated Solid FKM with improved chemical resistance up to +200℃


Product Details

These have a core of elastomer that is completely covered with a seamless sheath of fluorinated ethylene propylene.The core is normally fluorocarbon or silicone.


Encapsulated “O”rings are generally used when

1. Standard elastometric “O”ring has inadequate chemical resistance for a specific application

2. A solid PTFE “O”ring does not offer sufficient elasticity for reliable,long-term fluid sealing.
