-243 BLACK AFLAS 80D O-RING

Part number A80243 is an AS568-243 black Aflas (TFE/P) 80 Shore A O-Ring built to an inside diameter of 4.109 in (104.37 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.387 in (111.43 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to amines and corrosion inhibitors, brake fluids and phosphate esters, and hot water. That behavior comes from the compound itself: Aflas (TFE/P) is specified for exceptional resistance to amine-based additives and strong resistance to rapid gas decompression. 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 low-temperature dynamic service or aromatic hydrocarbons are present.

Common environments for this compound include downhole tooling, oil and gas production, and power generation.

This item is sold individually under part number A80243. Unit weight is approximately 0.0058 g and nominal inside diameter is listed as 4 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
