-155 BLACK AFLAS 80D O-RING

Part number A80155 is an AS568-155 black Aflas (TFE/P) 80 Shore A O-Ring built to an inside diameter of 3.987 in (101.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.193 in (106.5 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Aflas (TFE/P) delivers high-temperature steam capability that most fluoroelastomers cannot match and exceptional resistance to amine-based additives. It resists brake fluids and phosphate esters, strong bases, and amines and corrosion inhibitors. Continuous operating temperature is published at -25°F (-31.7°C) to 450°F (232.2°C). It is not the right choice where aromatic hydrocarbons or low-temperature dynamic service are present.

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