Product Specification

-
Ordered as A80428, this is an AS568-428 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 4.85 in (123.19 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.4 in (137.16 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Aflas (TFE/P) is known for high-temperature steam capability that most fluoroelastomers cannot match and strong resistance to rapid gas decompression. Expect good resistance to strong bases, amines and corrosion inhibitors, and high-temperature steam. Continuous operating temperature is published at -25°F (-31.7°C) to 450°F (232.2°C). It is not the right choice where low-temperature dynamic service or aromatic hydrocarbons are present.

You will find this material specified across downhole tooling, chemical processing, and power generation.

This item is sold individually under part number A80428. Unit weight is approximately 25.2571 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
