-049 BLACK AFLAS 80D O-RING

APG stocks the A80049, an AS568-049 black Aflas (TFE/P) 80 Shore A O-Ring built to an inside diameter of 4.989 in (126.72 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.129 in (130.28 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against sour gas and hydrogen sulfide, brake fluids and phosphate esters, and strong bases. That behavior comes from the compound itself: Aflas (TFE/P) is widely chosen for proven performance in aggressive downhole environments and exceptional resistance to amine-based additives. Rated temperature range runs from -25°F (-31.7°C) to 450°F (232.2°C) in continuous service. Exposure to aromatic hydrocarbons or some chlorinated solvents will shorten service life.

Maintenance and OEM teams specify it across downhole tooling, geothermal equipment, and power generation.

This item is sold individually under part number A80049. Unit weight is approximately 1.6473 g and nominal inside diameter is listed as 5 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.
