## Summary description

Expansion tank Aqua-Computer ULTITUBE D5 200 PRO is an add-on reservoir designed for D5-series pumps. It provides a 200 ml capacity chamber to simplify filling, air separation and maintenance of closed-loop liquid cooling systems. The ULTITUBE mounts inline with D5 pumps to improve coolant handling and enable easier bleeding and refilling in desktop water-cooling setups.

## Long description

The Aqua-Computer ULTITUBE D5 200 PRO expansion tank is an add-on reservoir designed specifically for inline installation with D5-series pumps. With a 200 ml chamber, it facilitates filling, air separation and maintenance of closed-loop liquid cooling loops in desktop PC water-cooling systems. The compact cylindrical design connects directly to the pump’s inlet or outlet, allowing controlled coolant management without major changes to the existing loop layout.
Advantages
The ULTITUBE D5 200 PRO provides a dedicated small-capacity reservoir that simplifies bleeding and refilling procedures, reducing trapped air and improving flow stability. Its inline mounting minimizes additional tubing runs and keeps the cooling loop compact while offering a visible coolant chamber for quick inspection. The construction is intended to be compatible with common D5 pump form factors and materials used in PC water-cooling, providing a practical solution when more convenient access to coolant is required.
Suitable for
Desktop PC custom water-cooling systems using a D5-series pump
Systems that require easier bleeding and air separation
Builds where compact inline reservoirs are preferred to top-mounted reservoirs
Maintenance tasks such as refilling and loop flushing
Key specifications
Reservoir capacity: 200 ml
Inline mounting compatible with D5-series pump flow path
Cylindrical compact form factor designed for minimal additional tubing
Transparent or partly transparent chamber for visual coolant level inspection
Materials suitable for standard PC coolant fluids
How to use
Mount the ULTITUBE D5 200 PRO inline with the D5 pump by replacing or inserting it into the pump’s inlet or outlet connection according to the pump and reservoir orientation. Ensure all fittings are tightened to avoid leaks and verify flow direction matches the intended loop. When filling the loop, use the ULTITUBE as the primary filling point to feed coolant into the system slowly, allowing air to rise into the chamber for separation. After filling, run the pump at low speed to purge remaining air, then top up through the reservoir until stable coolant level is reached.
Usage recommendations
Use compatible fittings and tubing rated for PC liquid cooling, inspect seals and O-rings during installation, and perform leak tests before long runtime. For effective air removal, incline the system slightly or operate the pump under controlled speed settings while filling. Avoid exposure to aggressive fluids not specified for PC cooling and follow manufacturer guidance for maintenance intervals.
