Acrylic Hardtube Barrow YK16-12 16/12 mm 500 mm Transparent

Acrylic hardtube Barrow YK16-12 is a transparent rigid tubing with outer/inner diameters 16/12 mm and a length of 500 mm, created for custom PC liquid cooling loops. The clear acrylic construction provides a stable, shape-retaining conduit for coolant while allowing visual monitoring of flow and fluid condition. This hardtube is compatible with standard 16 mm outer-diameter fittings and can be cut and bent to match radiator, pump and reservoir layouts in desktop water-cooling systems.

Advantages

The acrylic material offers high rigidity and dimensional stability, maintaining tube shape under pressure and temperature variations typical for PC cooling. Transparency enables easy inspection for colorants, debris and air bubbles. The 16/12 mm diameter combination balances flow capacity with compact routing in confined cases, and the 500 mm length reduces the need for multiple joints in mid-size builds. Smooth inner walls reduce turbulence and help maintain consistent flow rates.

Suitable for

• Custom PC liquid cooling loops in gaming and workstation desktops
• Routing between radiators, pumps, reservoirs and water blocks
• Visible coolant runs where visual appearance and monitoring are important
• Systems requiring rigid tubing that holds bent or shaped runs

Key specifications

• Material: transparent acrylic (rigid hardtube)
• Outer diameter: 16 mm
• Inner diameter: 12 mm
• Length: 500 mm
• Compatibility: standard 16 mm outer-diameter liquid cooling fittings
• Surface finish: smooth inner wall for reduced flow resistance

How to use

Measure and mark the required length for each run, then cut the acrylic tube squarely using a suitable tube cutter or fine-toothed saw. Deburr the inner and outer edges after cutting to ensure proper sealing with fittings. Heat and bend the tube using a controlled tubing heater or bending tool to form precise angles; allow the tube to cool and set before installing. Install with compatible compression or push-fit fittings rated for 16 mm outer diameter, ensuring seals are tight and leak-free. Pressure-test the loop according to standard PC water-cooling practices before powering the system.

Usage recommendations

Use compatible fittings and quality coolant formulated for PC liquid cooling. Avoid excessive localized heat during bending to prevent cracking, and allow gradual cooling to retain shape. Regularly inspect transparent tubing for discoloration or deposits and perform maintenance flushing as needed to preserve flow performance and appearance.
