568-141 FEP ENCAPSULATED SILICONE

The TES70141 is an AS568-141 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 2.3 in (58.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.506 in (63.65 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies. Supplementary detail from the product record: ORING 70 Durometer.

PTFE-Encapsulated Silicone is specified for strong resistance to permeation and a seamless PTFE jacket over a resilient silicone core. It resists steam, wide temperature swings, and nearly all process chemicals. 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 tight-radius dynamic flexing or installation over sharp edges are present.

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

Reference part number TES70141 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 5/16 inch.
