The Sun Hydraulics W6U/S (W6U/S) is a robust line mount manifold designed for hydraulic systems. This model features a 1.25 SAE C61 interface and is constructed with 6061-T651 aluminum, known for its exceptional corrosion resistance and strength. The manifold is built with a direct mount body type and includes one open cavity, specifically the T-22A cavity, making it suitable for various hydraulic applications where reliability and durability are essential. The port size of this component is specified as 1 1/4 Code 61, ensuring compatibility with standard hydraulic connections. Notably, the design does not incorporate anodizing due to considerations such as cost-effectiveness, logistical efficiency, and maintaining optimal fatigue life by avoiding potential crack initiation that anodizing might introduce. However, the non-anodized finish does not compromise performance in typical environments due to the inherent properties of the aluminum alloy used. Users must consider system pressure limitations since manifolds made from aluminum are not rated for pressures exceeding 3000 psi or 210 bar. This specification ensures safe operation within recommended parameters while offering reliable performance in hydraulic circuits requiring high flow capacity through standard line mount manifolds.

Show FAQ

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.
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.

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.
