*4146-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-146 black Buna-N (Nitrile) 70 Shore A quad profile supplied with an inside diameter of 2.612 in (66.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.818 in (71.58 mm), catalogued under part number HQ4146. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists hydraulic fluids, propane and butane, and greases and lubricants. Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

You will find this material specified across general industrial maintenance, construction equipment, and fluid power.

This item is sold individually under part number HQ4146. Nominal inside diameter is listed as 2 5/8. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
