Details
The Aquacomputer ULTITUBE D5 150 Reservoir (34091) is a 350 ml tube reservoir with a borosilicate glass tube and a base that takes a D5 pump motor, with two G1/4 ports. No pump is included: it needs a D5 pump to run, and the reservoir cannot be used without one.

Borosilicate glass tube
Every expansion tank in the ULTITUBE series is equipped with a tube made of borosilicate glass. Acrylic glass (Plexiglas) is often used for tube expansion tanks instead. In contrast, borosilicate glass has a very high hardness and scratch resistance, very low thermal expansion and excellent chemical and thermal resistance. The tube measures 65 mm in outer diameter, with a wall thickness of 5 mm. Metal rings of black anodized aluminum are firmly bonded to both ends, which keeps them connected to the tube, and they do not come into contact with the coolant or any other cooling medium.
Base and lid are made of resistant acetal and are screwed to the glass tube. After unscrewing the lid, a large opening is available for filling. The number in the name (50/100/150/200 across the Ultitube series) refers to the glass tube length in millimeters, so this product is the 150 mm version.
Filter and seals
Integrated at the bottom of the container sits a filter element of fine stainless steel wire mesh. In addition to functioning as a particle filter, it also separates air bubbles from the coolant. The element is held in a molded rubber part, and it can be rinsed out, for example under running tap water. The seal (gasket) in the upper area of the glass tube, below the lid, is a molded rubber part as well. It is designed for easy assembly and is therefore securely positioned in the right place when the lid is screwed on.
Pump mounting
All D5 pumps offered by Aqua Computer can be mounted into the bottom of the reservoir, as well as pumps of the same design (identically constructed) from other manufacturers. Aquacomputer says that when developing the reservoir, attention was paid to optimal flow behavior. In its words, the result is an extremely quiet pump, with noise and vibration reduced to a bare minimum. The pump is attached using a slim threaded ring of black anodized aluminum. It is not possible to run the reservoir with no pump fitted.
To fit a bare pump motor, place the gasket into the base and set the base on the motor. Then slide the mounting ring over the rear of the motor and screw it onto the base. On a D5 NEXT, take the controller unit off before fitting the ring and put it back afterward. If you have a complete D5 pump rather than a motor, disassemble it first: only the housing with its electronic components and the impeller are needed.
Installation in the case
Fastening material for mounting on a side / rear wall, or for a standing mounting on the bottom of the case, is included in the scope of delivery. Aquacomputer prefers the standing installation for stability reasons. For decoupling, four soft rubber decouplers (rubber buffers) come with it.
Combined with a D5 NEXT, the right angle mounting bracket from the box cannot be used. Instead, the reservoir can be installed standing directly on the D5 NEXT. Alternatively, a suitable bracket is available as an optional accessory, item D5 NEXT bracket (34111), not included. Brackets for standard fan mounting positions are also sold separately: the 120 mm bracket (34112) and the 140 mm bracket (34113).
What the loop needs
A D5 pump is required for operation and is not included in the delivery. A D5 pump core (41091) or a D5 NEXT (41118) fits, and more are in our D5 pumps section. Please note that the reservoir is supplied without connections, so order suitable fittings separately: the two G1/4 ports take two of them, from our fittings section. The return line goes to the port engraved IN, the other line to the remaining port.
Fill it with Double Protect Ultra or water. The same reservoir with a pump already fitted is the ULTITUBE D5 150 with D5 PWM pump (34098).

Notes
- Never use a coolant with solid micro particles: those in various opaque coolants damage the D5 pump bearing and may destroy the borosilicate glass tube.
- Use light force only when screwing in fittings, so the threads in the plastic base part are not damaged.
- To open the lid, hold the glass tube and turn the lid counter-clockwise, without tools and with moderate force only. Keep the gasket safe and place it on the glass tube before screwing the lid back on.
- Clean with a dry, soft cloth.
