Q-007 BUNA 70 Q RING

This quad-ring is supplied in AS568-007 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 0.145 in (3.68 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.285 in (7.24 mm), catalogued under part number QH70007. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists propane and butane, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or automotive brake fluid are present. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Typical settings include hydraulic and pneumatic systems, construction equipment, and fluid power.

Order part number QH70007, sold individually. Unit weight is approximately 0.0585 g and nominal inside diameter is listed as 5/32 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
