Reservoir tube Singularity Protium RT-100-60 — acrylic transparent reservoir tube for liquid cooling

Singularity Protium RT-100-60 is an acrylic transparent reservoir tube engineered for custom PC liquid cooling loops. The RT-100-60 serves as a rigid visual coolant channel compatible with Protium series fittings and mounting systems, providing clear flow visibility for monitoring coolant level, detecting air bubbles and inspecting flow paths. Its straight, transparent design supports aesthetic loop layouts while functioning as a functional filling and routing component within a custom cooling build.

Advantages

The acrylic construction offers high clarity and a smooth internal surface for unobstructed coolant visibility and simple cleaning. Designed for mechanical compatibility with Protium fittings and mounting hardware, the tube integrates into existing Protium layouts without requiring custom adapters. Its rigid form reduces the risk of deformation under mounting pressure and helps maintain consistent coolant routing for reliable performance and easy visual inspection.

Suitable for

• Custom PC liquid cooling loops requiring a straight transparent reservoir section
• Monitoring coolant level and flow path within windowed cases
• Visual loop layouts and aesthetic showcase builds
• Systems using Protium series fittings and mounting accessories

Key specifications

• Material: acrylic (transparent)
• Function: rigid reservoir tube for coolant routing and visual inspection
• Compatibility: intended for use with Protium series fittings and mounting systems
• Form factor: straight tube suitable for inline installation in custom loops
• Surface finish: smooth internal surface for unobstructed flow visibility

How to use

Install the RT-100-60 as part of a completed Protium-compatible loop by securing the tube with the corresponding Protium fittings and mounts. Ensure all sealing surfaces are clean and fittings are tightened according to the mounting hardware instructions to prevent leaks. Fill the loop with the chosen coolant and run leak tests before full operation; use the tube’s transparency to confirm coolant level and identify trapped air. When servicing, drain the loop and remove the tube following standard liquid cooling maintenance procedures.

Recommendations

Use non-corrosive, manufacturer-recommended coolants and perform periodic visual inspections through the transparent tube to identify sediment, discoloration or leaks. Avoid exposure to strong solvents or abrasive cleaners that can cloud acrylic; clean with mild detergent and soft cloth. When integrating into a compact layout, verify clearance and mounting torque to prevent stress on the tube.
