PTFE-Encapsulated Silicone is widely chosen for chemical inertness of PTFE with the wide temperature range of silicone and a non-contaminating, non-stick sealing surface. It resists wide temperature swings, steam, and strong acids and solvents. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.

You will find this material specified across cryogenic and high-temperature equipment, food and beverage processing, and chemical processing.

TES70444 ships individually. Nominal inside diameter is listed as 7 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
