Contact SupplierTelfon Encapsulated O-Rings with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments.
Teflon Encapsulated O-rings combine the resilience and sealing force of an elastomer with the chemical resistance of Teflon®i.e FEP or PFA on the outside with its chemical inertness and an elastomer (Silicone and Viton) on the inside for resilience
This unique combination forms a highly effective, long lasting seal for the most demanding applications.
Standard PTFE encapsulated O-Rings are comprised of FEP over silicone, Viton®, or EPDM, and can be used in temperatures from -75° to +400°F (-60° to +205°C) depending upon the choice of elastomer core.
