**4310-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-310 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 0.475 in (12.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.895 in (22.73 mm), catalogued under part number HQ4310. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Expect good resistance to water, greases and lubricants, and propane and butane. 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 strong acids are present. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

Common environments for this compound include general industrial maintenance, construction equipment, and agricultural equipment.

This item is sold individually under part number HQ4310. Nominal inside diameter is listed as 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
