Q-132 BUNA 70 Q RING

Ordered as QH70132, this is an AS568-132 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 1.737 in (44.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.943 in (49.35 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

It resists greases and lubricants, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or polar solvents.

You will find this material specified across construction equipment, automotive, and general industrial maintenance.

QH70132 ships individually. Unit weight is approximately 0.9492 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
