-424 BLACK AFLAS 80D O-RING

APG stocks the A80424, an AS568-424 black Aflas (TFE/P) 80 Shore A O-Ring measuring an inside diameter of 4.35 in (110.49 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.9 in (124.46 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to sour gas and hydrogen sulfide, high-temperature steam, and hot water. That behavior comes from the compound itself: Aflas (TFE/P) offers strong resistance to rapid gas decompression and high-temperature steam capability that most fluoroelastomers cannot match. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Exposure to some chlorinated solvents or aromatic hydrocarbons will shorten service life.

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

This item is sold individually under part number A80424. Nominal inside diameter is listed as 4 3/8 inch. Review your operating media and conditions against this specification before installation.
