The compound resists strong acids and solvents, nearly all process chemicals, and steam. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is specified for strong resistance to permeation and excellent recovery across extreme temperature cycling. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). Verify compatibility before use with tight-radius dynamic flexing or installation over sharp edges.

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

Reference part number TES70227 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
