*4118-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4118 is an AS568-118 black Buna-N (Nitrile) 70 Shore A 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. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

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