*568-350 FEP ENCAPSULATED SILICONE

Part number TES70350 is an AS568-350 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 4.6 in (116.84 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.02 in (127.51 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. This item is further identified as ORING 70 Durometer.

PTFE-Encapsulated Silicone is specified here for non-contaminating, non-stick sealing surface and seamless PTFE jacket over a resilient silicone core. This material stands up to strong acids and solvents, wide temperature swings, and steam. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.

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

TES70350 ships individually. Nominal inside diameter is listed as 4 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
