-447 BLACK AFLAS 80D O-RING

Ordered as A80447, this is an AS568-447 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists strong bases, high-temperature steam, and brake fluids and phosphate esters. That behavior comes from the compound itself: Aflas (TFE/P) delivers high-temperature steam capability that most fluoroelastomers cannot match and exceptional resistance to amine-based additives. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C).

You will find this material specified across power generation, oil and gas production, and chemical processing.
