Tubo rígido para refrigeração líquida Barrow Hardtube TB14-490 14/12mm 490mm preto

Barrow Hardtube TB14-490 is a 14/12mm rigid PC coolant tube in a 490mm length and black finish, made for custom liquid-cooling loops in desktop systems. The tubing is intended for use with acrylic/PETG hardline installations, offering a consistent outer and inner diameter for accurate coolant routing between radiators, pumps and water blocks. Its straight rigid form is suitable for builds that require clean, linear runs or precision-bent segments to achieve a tailored appearance and efficient flow.

Advantages

The rigid design delivers stable, vibration-resistant coolant lines that maintain shape over time and allow for precise alignment with fittings and components. Uniform 14mm outer and 12mm inner diameters ensure predictable flow characteristics and compatibility with fittings sized for those dimensions. The black finish provides a neutral, discreet look that integrates with many case interiors while concealing internal tubing details. The 490mm length reduces the need for multiple joints in longer runs, lowering the chance of leaks when properly installed.

Suitable for

• Custom desktop liquid-cooling loops using hardline tubing
• Builds requiring straight or bent rigid acrylic/PETG runs
• Systems where consistent tubing diameter is needed for fittings and flow planning
• Environments where a discreet black finish is preferred

Key specifications

• Outer diameter: 14 mm
• Inner diameter: 12 mm
• Length: 490 mm
• Material: rigid PC (polycarbonate) hardtube
• Finish: black

How to use

Measure the required run in your case and trim the tube to length using a suitable hardtube cutter or saw, then deburr the ends for a clean mating surface. If bending is required, follow recommended PC/bending procedures or use fittings designed for rigid tubing; ensure bends are made with appropriate heating tools and supports to avoid cracking. Insert compatible compression fittings or push-fit connectors onto the prepared ends and tighten according to the fitting manufacturer's torque guidance. Perform a pressure or leak test with the loop filled with coolant and the system off to confirm secure joints before powering the PC.

Recommendations

Store the tubing flat and protected from direct sunlight or high heat before installation. Use fittings rated for 14/12mm rigid tubing and verify compatibility with the pump, radiator and block ports. When bending or cutting, wear eye protection and follow tool safety instructions. Flush the loop and use appropriate coolant to prevent corrosion and deposits, and perform an initial leak test for several hours before normal operation.
