FEP Encapsulated Gaskets

TFE-O-SIL® silicone and Viton™ gaskets for cam lock couplings, encapsulated with FEP, are designed for use with practically all chemicals, even in the toughest corrosive environments. 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.

TFE-O-SIL Features:

Excellent Chemical Resistance - FEP is chemically inert to almost all industrial chemicals and solvents, even at elevated temperatures and pressures

Resiliency - Elastomeric cores provide an assured tight seal

Wide Temperature Range - Continuous service temperatures from
-75°F (-60°C) to +400°F (+205°C) for FEP & silicone,
-15°F (-26°C) to +400°F (+205°C) for FEP & Viton^™

Low Coefficient of Friction - Lubricious surface of FEP for easier gasket insertion

Nonstick Surface - Almost all substances release easily so cleanup is easier

Universal Seal - Handles practically any fluid. Eliminates matching the myriad elastomeric formulations with a specific requirement

Sanitary - Eliminates contamination associated with elastomeric gaskets.
