Q-114 BUNA 70 Q RING

This quad-ring is supplied in AS568-114 black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm), catalogued under part number QH70114. It provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer and economical choice for high-volume maintenance programs. Expect good resistance to propane and butane, petroleum-based oils, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life. 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, agricultural equipment, and hydraulic and pneumatic systems.

This item is sold individually under part number QH70114. Unit weight is approximately 0.3618 g and nominal inside diameter is listed as 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
