This quad-ring is supplied in AS568-362 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 6.225 in (158.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.645 in (168.78 mm), catalogued under part number QH70362. It provides a dual sealing band on each contact face for improved reliability.
This material stands up to greases and lubricants, petroleum-based oils, and many alcohols. Buna-N (Nitrile) delivers low compression set under sustained load, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present. The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.
Common environments for this compound include general industrial maintenance, automotive, and hydraulic and pneumatic systems.
Order part number QH70362, sold individually. Unit weight is approximately 13.539 g. Review your operating media and conditions against this specification before installation.
