PTFE-Encapsulated Silicone is valued for a seamless PTFE jacket over a resilient silicone core and a non-contaminating, non-stick sealing surface. It resists wide temperature swings, strong acids and solvents, and nearly all process chemicals. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Applications involving tight-radius dynamic flexing or installation over sharp edges call for a different compound.

Common environments for this compound include chemical processing, food and beverage processing, and pharmaceutical manufacturing.

This item is sold individually under part number TES70254. Nominal inside diameter is listed as 5 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
