*568-433 FEP ENCAPSULATED SILICONE

TES70433 is an AS568-433 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.025 in (153.04 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: ORING 70 Durometer.

The compound resists steam, wide temperature swings, and strong acids and solvents. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is specified for a non-contaminating, non-stick sealing surface and chemical inertness of PTFE with the wide temperature range of silicone. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.

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

Reference part number TES70433 when ordering; the item is sold individually. Nominal inside diameter is listed as 5 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
