A80904 is an AS568-904 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 0.351 in (8.92 mm), a cross section of 0.072 in (1.83 mm), and an outside diameter of 0.495 in (12.57 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Aflas (TFE/P) is known for strong resistance to rapid gas decompression and exceptional resistance to amine-based additives. It resists brake fluids and phosphate esters, high-temperature steam, and amines and corrosion inhibitors. Rated temperature range runs from -25°F (-31.7°C) to 450°F (232.2°C) in continuous service. Exposure to aromatic hydrocarbons or some chlorinated solvents will shorten service life.
Common environments for this compound include oil and gas production, downhole tooling, and geothermal equipment.
Stocked as A80904 and sold individually. Unit weight is approximately 0.1432 g and nominal inside diameter is listed as 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
