Stealkey Customs Cubetube SW10116 360 mm Acryl — Transparent Acrylic Reservoir Tube for PC Water Cooling

The Stealkey Customs Cubetube SW10116 360 mm Acryl is a transparent acrylic reservoir tube designed for custom PC water cooling loops. At 360 mm length, this tube-style reservoir provides a clear view of coolant flow and level, allowing easy visual monitoring of liquid condition. It integrates with pump and radiator layouts that accept tube reservoirs and is intended for enthusiasts and system builders creating or upgrading liquid-cooled desktop PCs.

Advantages

The transparent acrylic construction offers good optical clarity for visual inspection of coolant color and flow. Its standardized 360 mm length fits common case and loop layouts for tube reservoirs and enables modular placement alongside radiators and pumps. As a simple, passive reservoir component, the Cubetube minimizes moving parts and contributes to a clean, minimal loop appearance while allowing straightforward visual maintenance checks.

Suitable for

• Custom desktop PC water-cooling loops that use tube-style reservoirs
• System builders and enthusiasts installing or upgrading liquid cooling
• Setups where visual coolant monitoring is desired
• Configurations integrating separate pump and radiator assemblies

Key specifications

• Material: transparent acrylic
• Length: 360 mm
• Form factor: tube-style reservoir for PC water cooling
• Visible coolant channel for visual monitoring
• Compatible with tube-style reservoir mounting and loop layouts

How to use

Install the Cubetube reservoir in your loop according to your case layout and pump placement, ensuring all fittings and mounting hardware match the tube dimensions and thread types used in your system. Flush the reservoir and loop components before first use, and fill with a compatible coolant following the coolant manufacturer's instructions. Verify all connections are sealed, perform a leak test with the system powered off, then run the pump to circulate coolant and confirm unobstructed flow through the tube.

Recommendations

Inspect the reservoir periodically for signs of clouding, deposits, or discoloration. Use coolants and additives that are compatible with acrylic to avoid stress cracking or chemical damage. When performing maintenance, drain and flush the loop before removing the tube, and tighten fittings to the manufacturer's recommended torque to prevent leaks while avoiding overtightening.
