-443 BLACK AFLAS 80D O-RING

Ordered as A80443, this is an AS568-443 black Aflas (TFE/P) 80 Shore A O-Ring supplied with an inside diameter of 7.475 in (189.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.025 in (203.84 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Aflas (TFE/P) is specified here for proven performance in aggressive downhole environments and exceptional resistance to amine-based additives. It resists strong bases, high-temperature steam, and hot water. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C). Exposure to aromatic hydrocarbons or low-temperature dynamic service will shorten service life.

Maintenance and OEM teams specify it across oil and gas production, downhole tooling, and geothermal equipment.
