PTFE Encapsulated o-rings are o-rings consisting of a seamless and uniform PTFE FEP/PFA encapsulation/jacket which completely encloses a core rubber material.
This solution allows to combine the energising properties of an elatomeric “o-rings” (Silicone, Viton® , Epdm) with the resilience to extreme temperatures and hostile chemicals of Teflon® (FEP Fluoroetilene propilene or PFA Perfluoroalcoxy) Encapsulated o-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause failures.
