-394 BLACK AFLAS 80D O-RING

Part number A80394 is an AS568-394 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 25.36 in (644.14 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to hot water, brake fluids and phosphate esters, and high-temperature steam. That behavior comes from the compound itself: Aflas (TFE/P) is widely chosen for exceptional resistance to amine-based additives and excellent electrical insulating properties. Service temperature is rated from -25°F (-31.7°C) through 450°F (232.2°C). It is not the right choice where aromatic hydrocarbons or low-temperature dynamic service are present.

You will find this material specified across oil and gas production, downhole tooling, and power generation.

This item is sold individually under part number A80394. Nominal inside diameter is listed as 25 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
