PTFE-Encapsulated Silicone delivers a seamless PTFE jacket over a resilient silicone core and strong resistance to permeation. This material stands up to strong acids and solvents, nearly all process chemicals, and wide temperature swings. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. Exposure to installation over sharp edges or tight-radius dynamic flexing will shorten service life.

Common environments for this compound include cryogenic and high-temperature equipment, food and beverage processing, and pharmaceutical manufacturing.

This item is sold individually under part number TES70273. Nominal inside diameter is listed as 9 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
