Q-322 BUNA 70 Q RING

Ordered as QH70322, this is an AS568-322 black Buna-N (Nitrile) 70 Shore A 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. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

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.
