Q-454 BUNA 70 Q RING

APG stocks the QH70454, an AS568-454 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 12.475 in (316.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.025 in (330.84 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to propane and butane, hydraulic fluids, and petroleum-based oils. Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and automotive.
