This o-ring is supplied in AS568-274 black PTFE-Encapsulated Viton® 90 Shore A built to an inside diameter of 9.984 in (253.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.262 in (260.65 mm), catalogued under part number TEV80274. It remains the most cost-effective sealing element available for pressurized assemblies.
As a material, PTFE-Encapsulated Viton® is specified for long service life in aggressive chemical duty, excellent resistance to permeation and contamination. Expect good resistance to steam, aggressive oxidizers, and nearly all process chemicals. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Exposure to service requiring tight-radius dynamic flexing or installation over sharp edges without care will shorten service life.
Common environments for this compound include aggressive-media valves and pumps, chemical processing, and semiconductor equipment.
Stocked as TEV80274 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
