As a material, PTFE-Encapsulated Silicone delivers a seamless PTFE jacket over a resilient silicone core and strong resistance to permeation. The material holds up against wide temperature swings, strong acids and solvents, and nearly all process chemicals. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.

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

Order part number TES70225, sold individually. Nominal inside diameter is listed as 1 7/8 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.
