**4461-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4461, this is an AS568-461 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 15.955 in (405.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 16.505 in (419.23 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material holds up against petroleum-based oils, greases and lubricants, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or ozone and direct sunlight 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.

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

This item is sold individually under part number HQ4461. Nominal inside diameter is listed as 16 inch.
