*568-357 FEP ENCAPSULATED SILICONE

TES70357 is an AS568-357 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.895 in (149.73 mm). In service, this 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.

It resists nearly all process chemicals, steam, and strong acids and solvents. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is specified for strong resistance to permeation and a seamless PTFE jacket over a resilient silicone core. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Verify compatibility before use with tight-radius dynamic flexing or installation over sharp edges.

Typical settings include food and beverage processing, cryogenic and high-temperature equipment, and pharmaceutical manufacturing.

TES70357 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
