Ordered as A80381, this is an AS568-381 black Aflas (TFE/P) 80 Shore A O-Ring built to an inside diameter of 11.975 in (304.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 12.395 in (314.83 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Aflas (TFE/P) is specified here for high-temperature steam capability that most fluoroelastomers cannot match and exceptional resistance to amine-based additives. The compound resists hot water, brake fluids and phosphate esters, and amines and corrosion inhibitors. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C). Applications involving some chlorinated solvents or aromatic hydrocarbons call for a different compound.
Common environments for this compound include downhole tooling, chemical processing, and power generation.
Order part number A80381, sold individually. Nominal inside diameter is listed as 12 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
