Q-113 BUNA 70 Q RING

Part number QH70113 is an AS568-113 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The compound resists water, greases and lubricants, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ketones. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

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

This item is sold individually under part number QH70113. Unit weight is approximately 0.386 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
