**4313-366Y MINNESOTA RUBBER QUAD RING

The HQ4313 is an AS568-313 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring supplied with an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is known for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to many alcohols, water, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving ozone and direct sunlight or polar solvents call for a different compound.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, automotive, and construction equipment.

This item is sold individually under part number HQ4313. Check the compound against your process media, pressure and temperature before committing to a design.
