The reservoirs of the ULTITUBE series are equipped with a tube made of borosilicate glass: which in contrast to the Plexiglas often used for tube reservoirs, has a very high hardness and scratch resistance, very low thermal expansion and excellent chemical and thermal resistance. The glass tube has an outer diameter of 65 mm and a wall thickness of 5 mm. Both ends of the glass tube are firmly connected with metal rings made of black anodized aluminum that do not come into contact with the cooling medium. The base and lid of the ULTITUBE series are made of durable acetal and are screwed to the glass tube. After unscrewing the cap, there is a large opening for filling the expansion tank.

A filter element made of fine stainless steel wire mesh is integrated into the bottom of the container, which, in addition to its function as a particle filter, also separates air bubbles. The filter element is integrated into a molded rubber part and can be rinsed out under running water, for example. The seal in the upper area of ​​the glass tube is also designed as a molded rubber part for easy assembly and is therefore securely positioned when the lid is screwed on.

All D5 pumps offered by Aqua Computer can be mounted on the bottom of the expansion tank, as well as identical pumps from other manufacturers. When developing the expansion tank, attention was paid to optimal flow behavior, the result is extremely quiet and smooth-running operation of the pump. The pump is attached via a slim, black anodized aluminum ring. It is not possible to use the expansion tank without a pump.

 **Please Note**

Fastening material for mounting on a side/rear wall or vertical mounting are included. Reservoir connections not included, please order suitable connections seperately.
