APG stocks the QH70472, an AS568-472 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring supplied with an inside diameter of 22.94 in (582.68 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 23.49 in (596.65 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The compound resists propane and butane, water, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.

Maintenance and OEM teams specify it across automotive, fluid power, and general industrial maintenance.
