The Sun Hydraulics U2K/Y (Material Number: U2K/Y) is a line mount manifold specifically designed for high-flow hydraulic systems. This model features a 1.25 SAE C62 interface and is constructed as a sandwich mount through port, making it suitable for integration in complex hydraulic circuits where compact design and efficient flow management are essential. The manifold includes eight mounting holes with an M14x2,0 6H metric thread, each with a depth of 25.4 mm, ensuring secure installation in demanding environments. It also incorporates open cavities with T16A type ports measuring 1 1/4 inches according to Code 62 standards, facilitating high-capacity flow rates. The U2K/Y model is crafted from 6061T651 aluminum, known for its excellent corrosion resistance and strength-to-weight ratio, making it ideal for applications requiring durable yet lightweight components. This material choice ensures that the manifold can withstand harsh environmental conditions without the need for additional anodizing processes that might compromise its fatigue life or introduce unnecessary costs. This manifold is not rated for pressures exceeding 3000 psi (210 bar), which should be considered during system design to ensure safe operation within specified limits. The Sun Hydraulics U2K/Y provides robust performance in hydraulic applications requiring reliable fluid management and integration flexibility, supported by Sun's commitment to quality engineering and manufacturing excellence.

Show FAQ

How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
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%.

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.
