568-280 FEP ENCAPSULATED SILICONE

Ordered as TES70280, this is an AS568-280 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 13.984 in (355.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 14.262 in (362.25 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as ORING 70 Durometer.

This material stands up to steam, wide temperature swings, 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. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. Applications involving installation over sharp edges or tight-radius dynamic flexing call for a different compound.

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

This item is sold individually under part number TES70280. Nominal inside diameter is listed as 14 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
