A80256 is an AS568-256 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 5.734 in (145.64 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.012 in (152.7 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Aflas (TFE/P) is specified for high-temperature steam capability that most fluoroelastomers cannot match and strong resistance to rapid gas decompression. Expect good resistance to high-temperature steam, amines and corrosion inhibitors, and sour gas and hydrogen sulfide. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). It is not the right choice where low-temperature dynamic service or some chlorinated solvents are present.
It sees regular use in oil and gas production, power generation, and downhole tooling.
A80256 ships individually. Unit weight is approximately 0.0081 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
