*4022-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4022 is an AS568-022 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 0.989 in (25.12 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.129 in (28.68 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) offers low compression set under sustained load, strong abrasion and tear resistance. The compound resists propane and butane, water, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). 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 construction equipment, automotive, and general industrial maintenance.

HQ4022 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
