Q-334 BUNA 70 Q RING

This quad-ring is supplied in AS568-334 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm), catalogued under part number QH70334. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

This material stands up to hydraulic fluids, water, and petroleum-based oils. Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

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