4113-366Y MINNESOTA RUBBER QUAD RING

The HQ4113 is an AS568-113 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Expect good resistance to propane and butane, water, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Common environments for this compound include hydraulic and pneumatic systems, general industrial maintenance, and fluid power.

This item is sold individually under part number HQ4113. Nominal inside diameter is listed as 9/16 inch. Review your operating media and conditions against this specification before installation.
