568-240 FEP ENCAPSULATED SILICONE

Part number TES70240 is an AS568-240 red PTFE-Encapsulated Silicone 70 Shore A O-Ring built to an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 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 chemical inertness of PTFE with the wide temperature range of silicone and excellent recovery across extreme temperature cycling. The material holds up against strong acids and solvents, steam, and wide temperature swings. Published continuous service range is -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.

Maintenance and OEM teams specify it across pharmaceutical manufacturing, food and beverage processing, and chemical processing.

TES70240 ships individually. Nominal inside diameter is listed as 3 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
