APG stocks the H50176, an AS568-176 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 9.237 in (234.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.443 in (239.85 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Buna-N (Nitrile) is specified for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Expect good resistance to propane and butane, many alcohols, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.
