The Sun Hydraulics GCU (GCU) is a line mount hydraulic manifold designed for versatile applications requiring efficient fluid control. This inline body type manifold features an interface with no additional components, making it suitable for straightforward integration into hydraulic systems. It includes 11 mounting holes with a diameter of 0.33 inches (8.4 mm), accommodating through-depth installation, and utilizes a T-13A cavity configuration. The port size is standardized at 3/8 BSPP, ensuring compatibility with various hydraulic setups. Constructed from 6061-T651 aluminum, the manifold offers excellent corrosion resistance and durability, making it ideal for environments where these factors are critical. Despite its robust construction, the manifold is not anodized to avoid potential issues such as increased breakaway torque and reduced fatigue life associated with anodized surfaces. This decision underscores the importance of maintaining the structural integrity and longevity of the product under operational pressures up to 3000 psi (210 bar), which is the maximum rating for aluminum manifolds. The Sun Hydraulics GCU model is engineered to support high flow valves and can be utilized in custom integrated packages tailored to specific system requirements. Its design facilitates quick installation and reliable performance in demanding hydraulic applications, providing users with a dependable solution for managing fluid dynamics within their systems.

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.
