Q-361 BUNA 70 Q RING

QH70361 is an AS568-361 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 5.975 in (151.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.395 in (162.43 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

The material holds up against propane and butane, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers 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 two sealing bands per contact face rather than one.

It sees regular use in general industrial maintenance, construction equipment, and agricultural equipment.
