Part number A80903 is an AS568-903 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 0.301 in (7.65 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.429 in (10.9 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to brake fluids and phosphate esters, high-temperature steam, and hot water. Aflas (TFE/P) delivers excellent electrical insulating properties and proven performance in aggressive downhole environments. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Exposure to low-temperature dynamic service or aromatic hydrocarbons will shorten service life.
Maintenance and OEM teams specify it across oil and gas production, chemical processing, and power generation.
Order part number A80903, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
