Q-230 BUNA 70 Q RING

Ordered as QH70230, this is an AS568-230 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 2.484 in (63.09 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.762 in (70.15 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. It resists greases and lubricants, petroleum-based oils, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

You will find this material specified across agricultural equipment, construction equipment, and hydraulic and pneumatic systems.

QH70230 ships individually. Unit weight is approximately 2.557 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
