4383-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4383 is an AS568-383 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 13.975 in (354.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 14.395 in (365.63 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for low compression set under sustained load and most widely specified general-purpose sealing elastomer. The material holds up against hydraulic fluids, greases and lubricants, and petroleum-based oils. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

Typical settings include fluid power, automotive, and agricultural equipment.
