Encapsulated Viton O-Rings

FEP/PFA Encapsulated Silicone & Viton® O-Rings 


The Encapsulated O-ring consists of a Teflon (FEP/PFA) plastic layer and a rubber core, which effectively combines the elasticity and sealing properties of the rubber with the chemical resistance of Teflon, and the surface is dense and uniform without seams.
