Q-152 BUNA 70 Q RING

QH70152 is an AS568-152 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 3.237 in (82.22 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.443 in (87.45 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Expect good resistance to water, greases and lubricants, and propane and butane. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with strong acids or automotive brake fluid. 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 hydraulic and pneumatic systems, construction equipment, and agricultural equipment.
