4010-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4010 is an AS568-010 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 0.239 in (6.07 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.379 in (9.63 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material holds up against greases and lubricants, petroleum-based oils, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in polar solvents or ozone and direct sunlight. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

It sees regular use in fluid power, agricultural equipment, and general industrial maintenance.

Reference part number HQ4010 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
