Q-116 BUNA 70 Q RING

This quad-ring is supplied in AS568-116 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 0.737 in (18.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.943 in (23.95 mm), catalogued under part number QH70116. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists greases and lubricants, water, and petroleum-based oils. Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across agricultural equipment, fluid power, and general industrial maintenance.

Stocked as QH70116 and sold individually. Unit weight is approximately 0.467 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
