-390 BLACK AFLAS 80D O-RING

Part number A80390 is an AS568-390 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 20.953 in (532.21 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 21.373 in (542.87 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to amines and corrosion inhibitors, brake fluids and phosphate esters, and sour gas and hydrogen sulfide. That behavior comes from the compound itself: Aflas (TFE/P) is specified for excellent electrical insulating properties and high-temperature steam capability that most fluoroelastomers cannot match. Rated temperature range runs from -25°F (-31.7°C) to 450°F (232.2°C) in continuous service.

Common environments for this compound include chemical processing, oil and gas production, and geothermal equipment.

This item is sold individually under part number A80390. Check the compound against your process media, pressure and temperature before committing to a design. 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.
