Reservoir Tube Singularity Protium RT-250-60 — Acrylic transparent, 250 mm length

Singularity Protium RT-250-60 is a transparent acrylic reservoir tube designed for use in custom PC liquid cooling loops. At 250 mm length, the RT-250-60 provides a straight, clear channel for coolant circulation and visual monitoring, intended to integrate with compatible fittings, brackets and pump-reservoir assemblies in desktop water-cooling systems.

Advantages

The acrylic construction offers optical clarity and lightweight rigidity while maintaining resistance to common coolant additives. Its standardized 250 mm length supports predictable coolant capacity and loop planning. The smooth internal surface helps maintain steady flow and simplifies cleaning compared with irregular or porous materials. The transparent finish enables easy visual inspection of coolant level and flow without requiring additional lighting.

Suitable for

• Custom desktop PC liquid cooling loops that require a straight reservoir section
• Builds where visual coolant monitoring or display is required
• Compact or mid-size chassis layouts needing a defined 250 mm reservoir tube length
• Systems that pair with standard water-cooling fittings, clamps and mounting brackets

Key specifications

• Material: transparent acrylic
• Length: 250 mm
• Form factor: straight cylindrical reservoir tube
• Compatibility: designed for integration with standard liquid-cooling fittings and mounting hardware
• Finish: clear, polished surface for visual coolant inspection

How to use

Install the reservoir tube as part of a closed-loop cooling circuit following the fitting manufacturer’s instructions. Ensure end fittings and seals are compatible with acrylic and tightened to appropriate torque to avoid stress. Position the tube in the loop to allow proper flow direction and air bleeding, and secure it with suitable clamps or brackets to prevent movement. After installation, perform a pressure or leak test with coolant or deionized water before powering connected components.

Recommendations

Use coolants and additives that are compatible with acrylic to prevent clouding or chemical damage. Avoid overtightening fittings and protect the tube from sharp impacts. Periodically inspect for scratches or deposits and clean with non-abrasive, manufacturer-recommended solutions to maintain clarity and reliable flow monitoring.
