Q-322 BUNA 70 Q RING

Ordered as QH70322, this is an AS568-322 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm). The quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and most widely specified general-purpose sealing elastomer. This material stands up to many alcohols, greases and lubricants, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

It sees regular use in agricultural equipment, general industrial maintenance, and hydraulic and pneumatic systems.

QH70322 ships individually. Unit weight is approximately 3.394 g and nominal inside diameter is listed as 1 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
