Barrow rigid tubing 13/10 mm black 1 m RGBS-B for custom liquid cooling

Barrow rigid tubing 13/10 mm black 1 m RGBS-B is a solid, precision-cut tube intended for custom PC liquid cooling loops. The tube has a 13 mm outer diameter and a 10 mm inner diameter, supplied as a one-metre length in a matte black finish. It is designed to form a durable, leak-resistant channel for coolant between fittings, radiators and water blocks when used with compatible compression fittings and proper bending tools.

Advantages

The rigid tubing offers dimensional stability and a smooth internal surface for consistent coolant flow. Its black finish conceals internal tubing details and contributes to a clean, uniform appearance inside the system. The tube is cut to a standard one-metre length which simplifies planning and allows for measurable, repeatable runs. When installed correctly with appropriate fittings and bending equipment, the tubing forms solid, low-maintenance connections that resist deformation under normal operating conditions.

Suitable for

• Custom PC liquid cooling loops for desktop computers
• Neat, visible coolant routing in windowed or showcase cases
• Systems requiring straight runs or shaped bends using bending tools
• Connections between radiators, pumps, reservoirs and water blocks

Key specifications

• Outer diameter: 13 mm
• Inner diameter: 10 mm
• Length: 1 metre
• Color / finish: black
• Material type: rigid tubing suitable for liquid cooling applications

How to use

Measure and plan your loop layout before cutting the tube to ensure correct lengths and bend positions. Use a proper tube cutter to obtain square, burr-free ends and clean the inside surface before assembly. For shaped runs, heat and bend the tubing using an appropriate bending kit or bending mandrel to avoid kinks. Fit compatible compression fittings sized for 13/10 mm tubing, tighten according to the fitting manufacturer’s instructions, and pressure-test the assembled loop for leaks prior to powering the system.

Recommendations

Store the tubing flat and protected from direct sunlight and solvents prior to installation. Use only fittings and seals designed for 13/10 mm rigid tubing and follow safe bending practices: heat gradually, avoid overheating, and allow the tube to cool in position to retain the desired shape. Perform a thorough leak test after assembly and monitor coolant condition periodically to maintain system reliability.
