568-376 FEP ENCAPSULATED SILICONE

APG stocks the TES70376, an AS568-376 red PTFE-Encapsulated Silicone 70 Shore A O-Ring measuring an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 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.

PTFE-Encapsulated Silicone is specified here for excellent recovery across extreme temperature cycling and strong resistance to permeation. The material holds up against nearly all process chemicals, steam, and wide temperature swings. 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 installation over sharp edges or tight-radius dynamic flexing are present.

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

Reference part number TES70376 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
