Q-154 BUNA 70 Q RING

QH70154 is an AS568-154 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring with an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against petroleum-based oils, greases and lubricants, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Common environments for this compound include agricultural equipment, hydraulic and pneumatic systems, and automotive.

Stocked as QH70154 and sold individually. Unit weight is approximately 1.9617 g and nominal inside diameter is listed as 3 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
