APG stocks the H70418, an AS568-418 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 3.6 in (91.44 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.15 in (105.41 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance.

Exposure to strong acids or ozone and direct sunlight will shorten service life.
