-178 BLACK AFLAS 80D O-RING

Part number A80178 is an AS568-178 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 9.737 in (247.32 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.943 in (252.55 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to high-temperature steam, strong bases, and sour gas and hydrogen sulfide. Aflas (TFE/P) is known for exceptional resistance to amine-based additives and high-temperature steam capability that most fluoroelastomers cannot match. Rated temperature range runs from -25°F (-31.7°C) to 450°F (232.2°C) in continuous service. It should not be specified for service in low-temperature dynamic service or aromatic hydrocarbons.

You will find this material specified across power generation, geothermal equipment, and chemical processing.

A80178 ships individually. Unit weight is approximately 6.8228 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
