Stealkey Customs Cubetube SW10117 240 mm Acryl CPU/GPU coolant tube, 240 mm acrylic reservoir

Stealkey Customs Cubetube SW10117 240 mm Acryl is a 240 mm acrylic coolant tube and reservoir designed for custom PC liquid-cooling loops. The transparent acrylic body provides a clear channel for coolant circulation and visual level monitoring. It is intended for integration into CPU and GPU cooling circuits and fits systems that accept a straight 240 mm tubular reservoir as part of a loop layout.

Advantages

The acrylic construction delivers optical clarity for easy inspection of coolant condition and level. Its 240 mm length offers a compact reservoir option suitable for mid- to large-sized custom builds. The product is compatible with standard fittings used in custom liquid-cooling loops, enabling straightforward installation and integration into existing coolant circuits.

Suitable for

• Custom PC liquid-cooling loops for CPU cooling
• Custom PC liquid-cooling loops for GPU cooling
• Enthusiast builds requiring a compact 240 mm acrylic reservoir
• Systems where visual monitoring of coolant level is desired

Key specifications

• Material: Acrylic (transparent)
• Length: 240 mm
• Function: Coolant tube / reservoir for custom loops
• Compatibility: Designed for integration with standard liquid-cooling fittings and tubing used in CPU/GPU loops

How to use

Install the 240 mm acrylic tube into the loop using appropriate compression or rotary fittings matched to the tube diameter and the rest of the cooling system. Ensure seals and connections are tightened to prevent leaks and position the reservoir so it is accessible for filling and inspection. Fill the loop with suitable coolant according to the coolant manufacturer's instructions and perform a leak test before full operation.

Recommendations

Use coolants and additives that are compatible with acrylic materials and follow standard leak-testing procedures after installation. Avoid exposure to aggressive chemicals and prolonged direct sunlight to maintain optical clarity. Regularly inspect the reservoir for deposits or discoloration and service the loop as recommended by coolant and component manufacturers.
