*4153-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-153 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm), catalogued under part number HQ4153. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. It resists hydraulic fluids, propane and butane, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

Typical settings include automotive, agricultural equipment, and fluid power.

Stocked as HQ4153 and sold individually. Nominal inside diameter is listed as 3 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
