The A80409 is an AS568-409 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 2.475 in (62.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.025 in (76.84 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists sour gas and hydrogen sulfide, high-temperature steam, and strong bases. That behavior comes from the compound itself: Aflas (TFE/P) is known for strong resistance to rapid gas decompression and proven performance in aggressive downhole environments. Service temperature is rated from -25°F (-31.7°C) through 450°F (232.2°C). Exposure to aromatic hydrocarbons or low-temperature dynamic service will shorten service life.
Common environments for this compound include chemical processing, power generation, and oil and gas production.
Order part number A80409, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
