APG stocks the A80379, an AS568-379 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 10.975 in (278.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 11.395 in (289.43 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Aflas (TFE/P) is specified here for high-temperature steam capability that most fluoroelastomers cannot match and excellent electrical insulating properties. It resists sour gas and hydrogen sulfide, brake fluids and phosphate esters, and high-temperature steam. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Applications involving low-temperature dynamic service or aromatic hydrocarbons call for a different compound.

You will find this material specified across power generation, oil and gas production, and geothermal equipment.

Reference part number A80379 when ordering; the item is sold individually. Unit weight is approximately 32.295 g and nominal inside diameter is listed as 11 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
