Rigid PC Water Cooling Tube BitsPower Crystal Link 14/12mm OD/ID — 500mm transparent

BitsPower Crystal Link rigid PC water cooling tube, 14/12mm OD/ID and 500mm length, is a transparent hardline tube intended for custom liquid cooling loops in desktop computers. The tube provides a straight, consistent internal bore for coolant flow and is compatible with standard compression fittings and hardline bending accessories when used with appropriate tools and connectors. Its transparent construction allows visual monitoring of coolant condition and flow within a loop.

Advantages

The rigid Crystal Link tube offers precise outside and inside diameters (14 mm OD, 12 mm ID) for reliable sealing with compatible fittings, reducing the risk of leaks when installed correctly. Its transparent material makes it easy to inspect coolant clarity and detect air bubbles or sediment. The 500 mm length reduces the number of joints required for medium-length runs and simplifies layout planning for a clean, professional-looking build.

Suitable for

• Custom PC water cooling loops requiring hardline tubing
• Straight runs between components such as reservoir, pump, radiator, and water blocks
• Cut-to-length segments for precise routing in compact or full-size cases
• Installations using compression fittings compatible with 14/12 mm OD/ID tubing

Key specifications

• Outer diameter: 14 mm
• Inner diameter: 12 mm
• Length: 500 mm
• Material: transparent hardline (rigid) tube
• Compatibility: designed for use with compression fittings and hardline bending accessories when appropriate tools are used

How to use

Measure and mark the required length, then cut the tube squarely using a suitable hardline cutter or fine-toothed saw. Deburr the cut edges and dry-fit with the chosen compression fittings to confirm seating and alignment. When bending is required, use a hot-bending kit or a mandrel appropriate for the tube material and dimensions to achieve smooth bends without kinking. Assemble fittings following manufacturer torque guidelines and pressure-test the completed loop before introducing coolant.

Recommendations

Prior to final assembly, perform a leak and pressure test with distilled water or a recommended test fluid. Avoid excessive force on fittings; ensure tubing ends are clean and fully inserted into compression fittings. Use compatible coolant formulations to prevent material degradation and periodically inspect the transparent tube for discoloration or deposits.
