The A80470 is an AS568-470 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 20.955 in (532.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 21.505 in (546.23 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Aflas (TFE/P) offers exceptional resistance to amine-based additives and high-temperature steam capability that most fluoroelastomers cannot match. Expect good resistance to strong bases, high-temperature steam, and sour gas and hydrogen sulfide. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C). It is not the right choice where aromatic hydrocarbons or low-temperature dynamic service are present.
Common environments for this compound include power generation, downhole tooling, and geothermal equipment.
This item is sold individually under part number A80470. Unit weight is approximately 0.1156 g and nominal inside diameter is listed as 21 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
