Q-124 BUNA 70 Q RING

The QH70124 is an AS568-124 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.237 in (31.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.443 in (36.65 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Buna-N (Nitrile) is specified here for low compression set under sustained load and economical choice for high-volume maintenance programs. The compound resists greases and lubricants, petroleum-based oils, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

It sees regular use in general industrial maintenance, automotive, and agricultural equipment.

QH70124 ships individually. Unit weight is approximately 0.748 g. Check the compound against your process media, pressure and temperature before committing to a design.
