It delivers dependable bidirectional sealing in a compact groove envelope.
Aflas (TFE/P) is specified here for high-temperature steam capability that most fluoroelastomers cannot match and exceptional resistance to amine-based additives. The compound resists high-temperature steam, brake fluids and phosphate esters, and sour gas and hydrogen sulfide. Rated temperature range runs from -25°F (-31.7°C) to 450°F (232.2°C) in continuous service. It should not be specified for service in low-temperature dynamic service or aromatic hydrocarbons.
Maintenance and OEM teams specify it across downhole tooling, power generation, and chemical processing.
Stocked as A80272 and sold individually. Unit weight is approximately 12.1161 g and nominal inside diameter is listed as 9 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
