-903 BLACK AFLAS 80D O-RING

Part number A80903 is an AS568-903 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 0.301 in (7.65 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.429 in (10.9 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to brake fluids and phosphate esters, high-temperature steam, and hot water. Aflas (TFE/P) delivers excellent electrical insulating properties and proven performance in aggressive downhole environments. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Exposure to low-temperature dynamic service or aromatic hydrocarbons will shorten service life.

Maintenance and OEM teams specify it across oil and gas production, chemical processing, and power generation.
