-371 BLACK AFLAS 80D O-RING

Ordered as A80371, this is an AS568-371 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 8.475 in (215.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.895 in (225.93 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists sour gas and hydrogen sulfide, brake fluids and phosphate esters, and high-temperature steam. That behavior comes from the compound itself: Aflas (TFE/P) delivers strong resistance to rapid gas decompression and excellent electrical insulating properties. Service temperature is rated from -25°F (-31.7°C) through 450°F (232.2°C). Verify compatibility before use with aromatic hydrocarbons or low-temperature dynamic service.

Maintenance and OEM teams specify it across geothermal equipment, chemical processing, and downhole tooling.

Stocked as A80371 and sold individually. Unit weight is approximately 24.9593 g and nominal inside diameter is listed as 8 1/2 inch. Review your operating media and conditions against this specification before installation.
