-372 BLACK AFLAS 80D O-RING

This o-ring is supplied in AS568-372 black Aflas (TFE/P) 80 Shore A with an inside diameter of 8.725 in (221.62 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.145 in (232.28 mm), catalogued under part number A80372. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to sour gas and hydrogen sulfide, strong bases, and brake fluids and phosphate esters. That behavior comes from the compound itself: Aflas (TFE/P) is specified for exceptional resistance to amine-based additives and excellent electrical insulating properties. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C). Exposure to aromatic hydrocarbons or some chlorinated solvents will shorten service life.

Typical settings include geothermal equipment, power generation, and chemical processing.

A80372 ships individually. Unit weight is approximately 0.0284 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
