Product Specification

-
This o-ring is supplied in AS568-388 black Aflas (TFE/P) 80 Shore A supplied with an inside diameter of 18.953 in (481.41 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 19.373 in (492.07 mm), catalogued under part number A80388. It compresses into its gland to block fluid or gas migration across a joint.

The material holds up against sour gas and hydrogen sulfide, high-temperature steam, and strong bases. Aflas (TFE/P) is valued for excellent electrical insulating properties 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. Exposure to low-temperature dynamic service or aromatic hydrocarbons will shorten service life.

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

Order part number A80388, sold individually. Nominal inside diameter is listed as 19 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
