Q-165 BUNA 70 Q RING

Ordered as QH70165, this is an AS568-165 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 6.487 in (164.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.693 in (170 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Expect good resistance to hydraulic fluids, greases and lubricants, and propane and butane. Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

You will find this material specified across construction equipment, general industrial maintenance, and agricultural equipment.
