Reservoir for custom water cooling, Singularity Protium 200mm acrylic matte black

Singularity Protium 200mm acrylic matte black reservoir is a cylindrical coolant reservoir engineered for custom PC water cooling loops. The 200 mm acrylic tube provides visible coolant capacity while the matte black finish reduces reflective glare and blends with dark system themes. Designed for use as both a reservoir and distribution point, this component supports integration with standard fittings and tubing to facilitate filling, bleeding, and routine maintenance in compact and mid-size builds.

Advantages

The reservoir combines a compact cylindrical form factor with durable acrylic construction, offering a balance of capacity and space-efficiency for many chassis layouts. Its matte black surface minimizes visible smudges and reflections, and the clear internal volume allows users to monitor coolant level and flow. Built for straightforward plumbing, the design accommodates common compression and barbed fittings and simplifies loop routing and service access.

Suitable for

• Custom PC liquid cooling loops in compact or mid-tower cases
• Systems requiring a visible coolant reservoir with subdued exterior finish
• Builds that prioritize simple fill and bleed operations

Key specifications

• Reservoir type: cylindrical acrylic tube
• Length: 200 mm active reservoir section
• Finish: matte black exterior
• Material: clear acrylic tube with opaque matte coating
• Compatibility: standard liquid cooling fittings and tubing sizes
• Mounting: designed for case or bracket integration in typical custom builds

How to use

Install the reservoir in a secure location inside the case or on a compatible bracket, ensuring alignment with tubing and other loop components. Connect inlet and outlet ports with compatible fittings and tubing, then prime the loop by adding coolant until the reservoir indicates a stable level and all air pockets have been bled. Periodically inspect the reservoir for coolant level, clarity, and any signs of leaks or wear, and perform routine maintenance such as topping up coolant or flushing the loop as required.

Usage recommendations

Use fittings and tubing rated for your coolant type and system pressure. When installing, support the reservoir to prevent undue stress on fittings and follow manufacturer guidance for mounting and leak testing. For systems using dyes or additives, monitor for residue build-up and clean the reservoir during scheduled maintenance intervals.
