PTFE-Encapsulated Silicone is specified here for seamless PTFE jacket over a resilient silicone core and chemical inertness of PTFE with the wide temperature range of silicone. The compound resists wide temperature swings, steam, and strong acids and solvents. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.
You will find this material specified across food and beverage processing, cryogenic and high-temperature equipment, and chemical processing.
TES70128 ships individually. Nominal inside diameter is listed as 1 1/2 inch. Review your operating media and conditions against this specification before installation.
