Q-324 BUNA 70 Q RING

Part number QH70324 is an AS568-324 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring built to an inside diameter of 1.35 in (34.29 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.77 in (44.96 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load, reliable performance in both static and dynamic service. The compound resists greases and lubricants, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in strong acids or ketones.

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

Stocked as QH70324 and sold individually. Unit weight is approximately 3.438 g and nominal inside diameter is listed as 1 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
