568-173 FEP ENCAPSULATED SILICONE

Part number TES70173 is an AS568-173 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 8.487 in (215.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.693 in (220.8 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as ORING 70 Durometer.

As a material, PTFE-Encapsulated Silicone is widely chosen for a seamless PTFE jacket over a resilient silicone core and chemical inertness of PTFE with the wide temperature range of silicone. The material holds up against strong acids and solvents, steam, and nearly all process chemicals. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). It is not the right choice where tight-radius dynamic flexing or installation over sharp edges are present.

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