-355 BLACK AFLAS 80D O-RING

Ordered as A80355, this is an AS568-355 black Aflas (TFE/P) 80 Shore A O-Ring supplied with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.645 in (143.38 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Aflas (TFE/P) offers exceptional resistance to amine-based additives and high-temperature steam capability that most fluoroelastomers cannot match. It resists strong bases, high-temperature steam, and hot water. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). It is not the right choice where some chlorinated solvents or low-temperature dynamic service are present.

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

A80355 ships individually. Unit weight is approximately 15.6193 g and nominal inside diameter is listed as 5 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
