Q-326 BUNA 70 Q RING

The QH70326 is an AS568-326 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 1.6 in (40.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.02 in (51.31 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

This material stands up to greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Common environments for this compound include construction equipment, hydraulic and pneumatic systems, and general industrial maintenance.

Reference part number QH70326 when ordering; the item is sold individually. Unit weight is approximately 3.9463 g and nominal inside diameter is listed as 1 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
