Ordered as A80170, this is an AS568-170 black Aflas (TFE/P) 80 Shore A O-Ring built to an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists strong bases, sour gas and hydrogen sulfide, and brake fluids and phosphate esters. That behavior comes from the compound itself: Aflas (TFE/P) offers strong resistance to rapid gas decompression and high-temperature steam capability that most fluoroelastomers cannot match. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Verify compatibility before use with low-temperature dynamic service or some chlorinated solvents.
It sees regular use in chemical processing, downhole tooling, and geothermal equipment.
Stocked as A80170 and sold individually. Unit weight is approximately 5.4202 g and nominal inside diameter is listed as 7 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
