**4177-366Y MINNESOTA RUBBER QUAD RING

APG stocks the HQ4177, an AS568-177 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 9.487 in (240.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.693 in (246.2 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) offers reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists hydraulic fluids, petroleum-based oils, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving ozone and direct sunlight or ketones call for a different compound. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and fluid power.

This item is sold individually under part number HQ4177. Nominal inside diameter is listed as 9 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
