568-373 FEP ENCAPSULATED SILICONE

APG stocks the TES70373, an AS568-373 red PTFE-Encapsulated Silicone 70 Shore A O-Ring measuring an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as ORING 70 Durometer.

PTFE-Encapsulated Silicone is specified here for chemical inertness of PTFE with the wide temperature range of silicone and excellent recovery across extreme temperature cycling. This material stands up to nearly all process chemicals, strong acids and solvents, and wide temperature swings. 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.

Reference part number TES70373 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
