Part number A80235 is an AS568-235 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 3.109 in (78.97 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.387 in (86.03 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Aflas (TFE/P) delivers high-temperature steam capability that most fluoroelastomers cannot match and excellent electrical insulating properties. The compound resists high-temperature steam, sour gas and hydrogen sulfide, and strong bases. 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 aromatic hydrocarbons are present.
It sees regular use in oil and gas production, downhole tooling, and power generation.
Reference part number A80235 when ordering; the item is sold individually. Unit weight is approximately 4.0895 g and nominal inside diameter is listed as 3 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
