The Sun Hydraulics QCQ (Material Number: QCQ) is a line mount manifold designed for high-flow hydraulic applications. This model features a ninety-degree body type with no additional interface, making it suitable for various hydraulic systems requiring efficient flow management. The manifold includes two mounting holes threaded in M10x1.5 6H metric models, each with a depth of 15.7 mm (.62 inches), ensuring secure installation and stability within your system setup. It has one open cavity designed to accommodate T24A cartridges, and the port size is specified as 1 14 Code 61, which aligns with industry standards for reliable connectivity and performance. Constructed from 6061T651 aluminum, this manifold offers excellent corrosion resistance without the need for anodization, which can negatively impact fatigue life by initiating cracks under pressure. The choice of aluminum also provides a balance between strength and cost-effectiveness while maintaining machinability and availability in various forms. This makes the QCQ an ideal choice for applications where durability and longevity are critical under conditions that do not exceed a maximum system pressure of 3000 psi (210 bar). Overall, the Sun Hydraulics QCQ manifold is engineered to deliver robust performance in hydraulic systems while minimizing maintenance concerns associated with corrosion and material fatigue.

Show FAQ

Why does Sun use 6061 aluminum?	6061-T651 is relatively strong, relatively inexpensive, difficult to machine, readily available in all shapes and sizes and very corrosion resistant. 2024 is stronger and machines beautifully, but is expensive and falls to pieces in a corrosive environment.
Why doesn't Sun anodize their aluminum bodies?	Reasons to anodize: To increase corrosion resistance. Sun uses 6061-T651 aluminum. It is one of the most corrosion resistant aluminum alloys there is. Whether or not anodizing improves the corrosion resistance of 6061 aluminum is debatable. We have yet to have a manifold returned because of corrosion. Appearance (color). The 2 colors that would appeal to Sun would be blue or black. Unfortunately these are the colors that are hardest to do consistently. To provide a hard wear surface. Sun does not make parts-in-body valves. The manifold is just plumbing. We don't need a wear surface. Because everyone else does it. Bad reason. Reasons to not anodize: Cost. It's another process. Logistics. When you make tens of thousands of manifolds a month and you anodize hundreds, it's a problem. Consistency. See above. Stamping. After a body is anodized you cannot do any more stamping without making a mess.Inspection. Have you ever tried to look for burrs in a black anodized body? It's the old blackboard factory at night scenario. Torque. You will experience an increase in breakaway torque when removing items from an anodized manifold. Fatigue life. This is the best reason to not anodize. Fatigue failure is a very complex phenomenon. What it takes to initiate a crack is difficult to predict. What it takes to propagate a crack is readily defined. Anodizing produces a very thin, very hard, and very brittle surface on aluminum. The first time you pressurize an anodized aluminum manifold you have initiated fatigue cracks. Whether or not the stress is enough to propagate the cracks is a matter of pressure and manifold geometry. Anodizing an aluminum manifold grossly reduces the fatigue life by anywhere from 20% to 50%.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Notes:

Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
