All reservoirs of the ULTITUBE series are equipped with a borosilicate glass tube. In contrast to acrylic glass, which is often used for tube reservoirs, borosilicate glass is extremely hard and scratch-resistant, features superb thermal and chemical resistance and a very low thermal expansion. The glass tube has an outer diameter of 65 mm and a wall thickness of 5 mm. Black anodized aluminum rings are securely bonded to both ends of the glass tube, and the rings do not get into contact with the coolant. Base and lid of the ULTITUBE series reservoirs are made from resilient acetal and screwed to the glass tube. After unscrewing the lid, a large opening ensures easy filling.

At the bottom of the reservoir, an integrated stainless steel mesh filter element effectively separates both particles and air bubbles from the coolant. The mesh filter is integrated into a molded rubber part and can be rinsed with tap water. The gasket between glass tube and lid is also a molded rubber part, designed to be securely held in the right position during fastening of the lid.

The PRO version of the ULTITUBE D5 features a pressure equalization membrane, directly integrated into the lid of the reservoir. The membrane allows gases to pass and thereby continuously equalizes the internal pressure of the liquid cooling loop and the ambient pressure, while completely blocking coolant from leaking.
Also included in delivery is a RGBpx compatible LED ring with 13 addressable LEDs that can be used for effective illumination of the reservoir. An Aqua Computer device with RGBpx output is required for LED operation (for example D5 NEXT, not included in delivery). A connector at the end of the strip can be used to connect another RGBpx component consecutively.
For additional, vibration dampening fixation of the reservoir in the upper area of the glass tube, a fixation ring made from rubber with a stainless steel insert is included.

All D5 pumps produced by Aqua Computer can be installed into the base of the reservoir, additionally identically constructed pumps by other manufacturers. The reservoir has been designed for optimum flow characteristics, reducing noise and vibration of the pump to a bare minimum. The pump is secured using a slim threaded ring made from black anodized aluminum. The reservoir can not be used without a pump.

Mounting material for installation to a side/rear panel or to the bottom of a PC case is included in delivery. For decoupling, four soft rubber buffers are included.
