4016-366Y MINNESOTA RUBBER QUAD RING

HQ4016 is an AS568-016 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 0.614 in (15.6 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.754 in (19.15 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. It resists water, petroleum-based oils, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Common environments for this compound include agricultural equipment, fluid power, and construction equipment.

HQ4016 ships individually. Nominal inside diameter is listed as 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
