Q-046 BUNA 70 Q RING

Part number QH70046 is an AS568-046 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 4.239 in (107.67 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.379 in (111.23 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is specified here for low compression set under sustained load, reliable performance in both static and dynamic service. The compound resists petroleum-based oils, water, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

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

Stocked as QH70046 and sold individually. Unit weight is approximately 1.0865 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
