-344 BLACK AFLAS 80D O-RING

APG stocks the A80344, an AS568-344 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to sour gas and hydrogen sulfide, strong bases, and brake fluids and phosphate esters. That behavior comes from the compound itself: Aflas (TFE/P) delivers strong resistance to rapid gas decompression and excellent electrical insulating properties. Continuous operating temperature is published at -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.

It sees regular use in chemical processing, geothermal equipment, and power generation.

This item is sold individually under part number A80344. Unit weight is approximately 0.0129 g and nominal inside diameter is listed as 3 7/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
