H70FDA018 is an AS568-018 white Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.739 in (18.77 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.879 in (22.33 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present.
