-203 BLACK AFLAS 80D O-RING

The A80203 is an AS568-203 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 0.296 in (7.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.574 in (14.58 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to hot water, amines and corrosion inhibitors, and sour gas and hydrogen sulfide. Aflas (TFE/P) is widely chosen for proven performance in aggressive downhole environments and excellent electrical insulating properties. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Applications involving low-temperature dynamic service or aromatic hydrocarbons call for a different compound.

You will find this material specified across oil and gas production, power generation, and chemical processing.

A80203 ships individually. Unit weight is approximately 0.5477 g and nominal inside diameter is listed as 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
