TES70429 is an AS568-429 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 4.975 in (126.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.525 in (140.34 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope. This item is further identified as ORING 70 Durometer.
As a material, PTFE-Encapsulated Silicone is widely chosen for chemical inertness of PTFE with the wide temperature range of silicone and excellent recovery across extreme temperature cycling. This material stands up to steam, wide temperature swings, and strong acids and solvents. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). 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.
TES70429 ships individually. Nominal inside diameter is listed as 5 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
