Q-024 BUNA 70 Q RING

QH70024 is an AS568-024 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 1.114 in (28.3 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.254 in (31.85 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Expect good resistance to petroleum-based oils, propane and butane, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Common environments for this compound include hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.

QH70024 ships individually. Unit weight is approximately 0.2913 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
