*568-275 FEP ENCAPSULATED SILICONE

This o-ring is supplied in AS568-275 red PTFE-Encapsulated Silicone 70 Shore A measuring an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm), catalogued under part number TES70275. It creates a positive seal at flange, piston and rod interfaces without added hardware. The catalog record notes: ORING 70 Durometer.

The material holds up against steam, strong acids and solvents, and nearly all process chemicals. That behavior comes from the compound itself: PTFE-Encapsulated Silicone offers chemical inertness of PTFE with the wide temperature range of silicone and strong resistance to permeation. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Exposure to tight-radius dynamic flexing or installation over sharp edges will shorten service life.

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

This item is sold individually under part number TES70275. Nominal inside diameter is listed as 10 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
