Q-123 BUNA 70 Q RING

APG stocks the QH70123, an AS568-123 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The material holds up against water, propane and butane, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

Typical settings include fluid power, construction equipment, and agricultural equipment.
