*568-151 FEP ENCAPSULATED SILICONE

Part number TES70151 is an AS568-151 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 2.987 in (75.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.193 in (81.1 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint. Additional detail on this item: ORING 70 Durometer.

The compound resists strong acids and solvents, steam, and nearly all process chemicals. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is specified for a seamless PTFE jacket over a resilient silicone core and strong resistance to permeation. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Exposure to tight-radius dynamic flexing or installation over sharp edges will shorten service life.

Common environments for this compound include pharmaceutical manufacturing, chemical processing, and cryogenic and high-temperature equipment.

TES70151 ships individually. Nominal inside diameter is listed as 3 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
