APG stocks the H90470, an AS568-470 black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 20.955 in (532.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 21.505 in (546.23 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is valued for low compression set under sustained load and an economical choice for high-volume maintenance programs. Expect good resistance to water, propane and butane, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.
