Tube BitsPower BP-NCPLT12-L500 — PETG transparent, 12 mm diameter, 50 cm length

BitsPower BP-NCPLT12-L500 is a rigid transparent PETG tube designed for custom computer liquid cooling loops. Manufactured from PETG (polyethylene terephthalate glycol-modified), the tube provides a clear coolant path with a 12 mm outer diameter and a 50 cm length. The stiff construction offers shape retention for visible loop runs and is compatible with common compression fittings used in PC water-cooling systems.

Advantages

The PETG material combines good transparency with mechanical rigidity, making coolant flow and internal components clearly visible while maintaining the tube's shape. Its 12 mm outer diameter ensures compatibility with fittings and aesthetic consistency in standard hard-line builds. The 50 cm length reduces the need for multiple joins in medium-sized systems and simplifies routing for many loop layouts. PETG is also easier to cut and bend with appropriate tools compared with some other rigid plastics, allowing precise custom installations.

Suitable for

• Custom PC liquid cooling loops with visible tubing runs
• Connections between radiators, reservoirs and pumps in desktop systems
• Hard-line builds requiring a 12 mm outer diameter tube

Key specifications

• Material: PETG (polyethylene terephthalate glycol)
• Outer diameter: 12 mm
• Length: 50 cm
• Finish: Transparent / clear
• Rigid (hard-line) tube suitable for cutting and forming with appropriate tools

How to use

Measure required lengths and mark cut points before cutting the PETG tube with a fine-toothed saw or tube cutter to ensure clean, square ends. Deburr the inner and outer edges after cutting to ensure proper sealing. When bending or shaping, use a heat source and bending jig designed for PETG to achieve smooth radii without collapsing the tube. Install the tube into compatible compression fittings, confirming that the fitting's inner diameter and gasket are suitable for a 12 mm outer diameter tube. Tighten fittings to the manufacturer's recommended torque and pressure-test the completed loop before powering the PC.

Recommendations

Use coolant formulas compatible with PETG and avoid aggressive solvents or cleaners. Work in a well-ventilated area when heating or cutting, and wear appropriate personal protective equipment. For long-term clarity, perform routine maintenance and replace tubing if signs of discoloration, clouding or microcracks appear.
