*4118-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4118 is an AS568-118 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 0.862 in (21.89 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.068 in (27.13 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. It resists greases and lubricants, hydraulic fluids, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

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

This item is sold individually under part number HQ4118. As always, verify media compatibility and operating conditions against the requirements of your specific application.
