568-229 FEP ENCAPSULATED SILICONE

Part number TES70229 is an AS568-229 red PTFE-Encapsulated Silicone 70 Shore A O-Ring built to an inside diameter of 2.359 in (59.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.637 in (66.98 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as ORING 70 Durometer.

Expect good resistance to strong acids and solvents, wide temperature swings, and nearly all process chemicals. PTFE-Encapsulated Silicone is known for excellent recovery across extreme temperature cycling and chemical inertness of PTFE with the wide temperature range of silicone. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.

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