PTFE-Encapsulated Silicone is specified here for seamless PTFE jacket over a resilient silicone core and strong resistance to permeation. It resists strong acids and solvents, steam, and wide temperature swings. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). Exposure to installation over sharp edges or tight-radius dynamic flexing will shorten service life.

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

Stocked as TES70369 and sold individually. Nominal inside diameter is listed as 8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
