-050 BLACK AFLAS 80D O-RING

Part number A80050 is an AS568-050 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 5.239 in (133.07 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.379 in (136.63 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists high-temperature steam, strong bases, and brake fluids and phosphate esters. Aflas (TFE/P) is specified for exceptional resistance to amine-based additives 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). Applications involving low-temperature dynamic service or aromatic hydrocarbons call for a different compound.

Maintenance and OEM teams specify it across downhole tooling, oil and gas production, and power generation.

Reference part number A80050 when ordering; the item is sold individually. Unit weight is approximately 0.002 g and nominal inside diameter is listed as 5 1/4 inch. Review your operating media and conditions against this specification before installation.
