Barrow Acrylic Hardtube YK16-12L 16/12 mm transparent 1000 mm

Barrow Acrylic Hardtube YK16-12L 16/12 mm transparent 1000 mm is a rigid acrylic tube intended for custom liquid-cooling loops in personal computers and electronic cooling systems. With an outer diameter of 16 mm and an inner diameter of 12 mm, this transparent 1000 mm tube provides a stable coolant channel that permits visual inspection and clean routing. The hardtube is compatible with 16/12 mm hardline fittings and can be cut, deburred and heat-formed by experienced users to fit bespoke loops.

Advantages

The acrylic construction combines clarity and rigidity, allowing neat, straight runs and visible coolant flow. Its dimensional tolerance supports a secure fit with standard 16/12 mm hardline fittings for leak-resistant connections when installed correctly. The 1000 mm length reduces the number of joints needed for mid-to-large builds, and the material is suitable for bending with hot-air techniques used in custom water-cooling workflows.

Suitable for

• Custom PC liquid-cooling loops using 16/12 mm hardline systems
• Electronics cooling where a rigid, transparent coolant path is required
• Prototype rigs and test benches that need visible coolant flow
• Mod builds requiring precise, straight coolant runs or shaped bends

Key specifications

• Material: acrylic (rigid)
• Outer diameter: 16 mm
• Inner diameter: 12 mm
• Length: 1000 mm
• Color/finish: transparent/clear

How to use

Measure the required run length and mark cutting points on the tube. Cut with an appropriate tube cutter or fine saw and deburr both inner and outer edges to avoid flow restriction and sealing issues. For bending, apply controlled heat using a hot-air gun or an oven method while supporting the tube to achieve the desired radius; allow the acrylic to cool slowly to preserve shape. Fit to compatible 16/12 mm hardline fittings using the manufacturer-recommended O-rings or compression rings, and perform a pressure or leak test with the loop filled before powering the system.

Recommendations

Handle the acrylic tube with care to avoid scratches and micro-cracks. Use compatible fittings and sealing components sized for 16/12 mm tubing, and ensure all joints are clean and free of debris before assembly. When heating for bending, keep temperature and exposure time consistent to prevent deformation. Perform a full leak test under low pressure and monitor coolant quality periodically to maintain transparent appearance and reliable operation.
