4467-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-467 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 18.955 in (481.46 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 19.505 in (495.43 mm), catalogued under part number HQ4467. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists water, petroleum-based oils, and propane and butane. Buna-N (Nitrile) is known 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). It is not the right choice where polar solvents or ozone and direct sunlight are present. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

It sees regular use in construction equipment, hydraulic and pneumatic systems, and agricultural equipment.

This item is sold individually under part number HQ4467. Nominal inside diameter is listed as 19 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
