Q-222 BUNA 70 Q RING

This quad-ring is supplied in AS568-222 black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 1.484 in (37.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.762 in (44.75 mm), catalogued under part number QH70222. It seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material holds up against greases and lubricants, propane and butane, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or automotive brake fluid. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

You will find this material specified across general industrial maintenance, automotive, and hydraulic and pneumatic systems.

Stocked as QH70222 and sold individually. Unit weight is approximately 1.5368 g and nominal inside diameter is listed as 1 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
