4017-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-017 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 0.676 in (17.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.816 in (20.73 mm), catalogued under part number HQ4017. It provides a dual sealing band on each contact face for improved reliability.

The compound resists greases and lubricants, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Common environments for this compound include fluid power, construction equipment, and agricultural equipment.

Reference part number HQ4017 when ordering; the item is sold individually. 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.
