4224-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4224 is an AS568-224 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 1.734 in (44.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.012 in (51.1 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

The material holds up against hydraulic fluids, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for low compression set under sustained load, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or automotive brake fluid are present.

Typical settings include fluid power, hydraulic and pneumatic systems, and agricultural equipment.

This item is sold individually under part number HQ4224. Nominal inside diameter is listed as 1 3/4 inch.
