Q-392 BUNA 70 Q RING

Ordered as QH70392, this is an AS568-392 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material holds up against greases and lubricants, hydraulic fluids, and propane and butane. Published continuous service range is -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.

Maintenance and OEM teams specify it across fluid power, construction equipment, and automotive.

QH70392 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
