4226-366Y MINNESOTA RUBBER QUAD RING

APG stocks the HQ4226, an AS568-226 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 1.984 in (50.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.262 in (57.45 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The compound resists petroleum-based oils, hydraulic fluids, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ozone and direct sunlight or automotive brake fluid. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

Typical settings include fluid power, general industrial maintenance, and agricultural equipment.

Stocked as HQ4226 and sold individually. Nominal inside diameter is listed as 2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
