568-431 FEP ENCAPSULATED SILICONE

Part number TES70431 is an AS568-431 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.775 in (146.69 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. Additional detail on this item: ORING 70 Durometer.

It resists wide temperature swings, strong acids and solvents, and nearly all process chemicals. That behavior comes from the compound itself: PTFE-Encapsulated Silicone delivers excellent recovery across extreme temperature cycling and a non-contaminating, non-stick sealing surface. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service.

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

TES70431 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
