Reservoir (200 mm) Singularity Protium 2.0 — Acetal, black (SC-P2-200R-ALBK)

Singularity Protium 2.0 200 mm reservoir in acetal black is a cylindrical liquid-cooling reservoir designed for custom PC watercooling loops. The 200 mm length is suited to mid-to-large tower builds and provides coolant containment, visible fill level monitoring and integration points for fittings and pump tops to support circulation and maintenance operations.

Advantages

The acetal construction offers chemical resistance and dimensional stability while maintaining a matte black appearance that blends with a variety of system aesthetics. The 200 mm form factor supplies increased internal volume compared with smaller reservoirs, reducing the need for frequent top-ups and improving air collection during bleeding. The reservoir is compatible with common fittings and pump-top mounting methods, enabling straightforward integration into existing custom loops without altering other core components.

Suitable for

• Custom PC watercooling loops in mid-tower and full-tower systems
• Builds requiring increased coolant volume for extended circulation
• Systems where a discreet, matte-black reservoir aesthetic is preferred
• Setups that use external pump tops and standard G1/4 or similar threaded fittings

Key specifications

• Material: acetal (black)
• Form factor: cylindrical reservoir
• Length: 200 mm
• Intended use: PC liquid-cooling coolant containment and monitoring
• Compatibility: designed for use with standard watercooling fittings and pump tops

How to use

Install the reservoir into your loop following the case or mounting bracket manufacturer’s guidance, ensuring secure attachment and correct orientation for inlet and outlet ports. Connect appropriate fittings and hoses to the reservoir ports, verify thread compatibility and seal with suitable PTFE or gasket methods as required. When integrating with a pump top, align and mount the pump according to the pump manufacturer’s instructions to ensure proper flow direction. Fill the loop slowly with coolant through the reservoir, run the pump at low speed to circulate and bleed trapped air, and top up until the reservoir maintains the desired level.

Recommendations

For best long-term performance, use coolant formulated for PC liquid cooling, periodically inspect fittings and seals for leaks, and perform regular maintenance such as coolant replacement and system flushing. When routing tubing, minimize sharp bends and strain on fittings; keep the reservoir accessible for filling and bleeding operations.
