Q-223 BUNA 70 Q RING

APG stocks the QH70223, an AS568-223 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The compound resists propane and butane, hydraulic fluids, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Typical settings include construction equipment, hydraulic and pneumatic systems, and agricultural equipment.

Reference part number QH70223 when ordering; the item is sold individually. Unit weight is approximately 1.6398 g and nominal inside diameter is listed as 1 5/8 inch.
