568-213 FEP ENCAPSULATED SILICONE

Part number TES70213 is an AS568-213 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 0.921 in (23.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.199 in (30.45 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Supplementary detail from the product record: ORING 70 Durometer.

Expect good resistance to nearly all process chemicals, strong acids and solvents, and wide temperature swings. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is widely chosen for a seamless PTFE jacket over a resilient silicone core and strong resistance to permeation. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). Applications involving installation over sharp edges or tight-radius dynamic flexing call for a different compound.

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