PTFE-Encapsulated Silicone is known for chemical inertness of PTFE with the wide temperature range of silicone and strong resistance to permeation. Expect good resistance to strong acids and solvents, steam, and nearly all process chemicals. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Applications involving installation over sharp edges or tight-radius dynamic flexing call for a different compound.

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

Reference part number TES70245 when ordering; the item is sold individually. Nominal inside diameter is listed as 4 3/8 inch.
