Ordered as HQ4211, this is an AS568-211 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring supplied with an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and low compression set under sustained load. Expect good resistance to many alcohols, propane and butane, and greases and lubricants. 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.

You will find this material specified across general industrial maintenance, automotive, and agricultural equipment.

HQ4211 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
