Q-011 BUNA 70 Q RING

Ordered as QH70011, this is an AS568-011 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring with an inside diameter of 0.301 in (7.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.441 in (11.2 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The compound resists propane and butane, water, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and agricultural equipment.
