Q-134 BUNA 70 Q RING

Ordered as QH70134, this is an AS568-134 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

The material holds up against hydraulic fluids, petroleum-based oils, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with automotive brake fluid or ozone and direct sunlight. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

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