These gaskets combine the best qualities of two materials to form a superior seal: Elastomer as the core for resilience, and FEP on the outside for chemical resistance. Not an envelope gasket, the elastomeric core of every TFE-O-SIL® gasket is fully encased. - Maintains reliable sealing across a broad temperature range, suitable for various industrial applications. - Exceptional chemical resistance and durability in harsh environments with FEP Encapsulated Gaskets.
