*Q-023 BUNA 70 Q RING

Part number QH70023 is an AS568-023 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.051 in (26.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.191 in (30.25 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The compound resists petroleum-based oils, water, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

It sees regular use in general industrial maintenance, construction equipment, and fluid power.

Reference part number QH70023 when ordering; the item is sold individually. Unit weight is approximately 0.2807 g and nominal inside diameter is listed as 1 1/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
