The Sun Hydraulics FTU (FTU) is a versatile hydraulic subplate designed for ISO 03 interface applications. This subplate features a P to T manifold T port configuration and is constructed with an open cavity designated as T10A. It accommodates a 3/8 BSPP port size, making it suitable for various hydraulic systems requiring efficient fluid transfer. The body of the subplate is crafted from 6061T651 aluminum, known for its excellent corrosion resistance and durability, although it is not anodized to avoid potential issues such as increased breakaway torque and reduced fatigue life. This material choice ensures the subplate can withstand pressures up to 3000 psi (210 bar), provided the system's design takes into account the limitations of aluminum manifolds. The FTU model is specifically designed to be mounted on top of a reservoir, with an NPTF tank port that supports a down pipe connection below the oil level, ensuring optimal fluid management within hydraulic systems. The inclusion of O-rings in the tank port and mounting holes enhances sealing efficiency against mounting surfaces, thus preventing leaks and maintaining system integrity.

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:

This subplate is designed to mount to the top of a reservoir. Tank is an NPTF port to accommodate a down pipe to drop the connection below the oil level. The tank port and mounting holes are supplied with O rings to seal to the mounting surface.
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.
