Tube for computer cooling system BitsPower BP-NCPLT14-L500 — PETG, 1.4 cm diameter, 50 cm length, transparent

Rigid PETG tube by BitsPower, model BP-NCPLT14-L500, designed for custom PC liquid cooling loops. The transparent polyethylene terephthalate glycol construction provides clear visibility of coolant flow and a smooth surface that accepts bending and polishing. With a 14 mm outer diameter and 50 cm length, this tube is intended for routing coolant between water blocks, radiators, reservoirs and pumps in looped cooling circuits and for replacing or extending existing PETG runs.

Advantages

The PETG material combines rigidity with moderate flexibility for precise bends and durable performance. Transparency allows visual inspection of coolant and quick detection of air bubbles or contamination. The consistent wall finish supports leak-free fittings when cut and deburred correctly. Its standardized diameter suits common compression fittings for sealed custom loops.

Suitable for

• Custom PC liquid cooling loops connecting blocks, radiators and pumps
• Replacing or extending existing PETG tubing runs
• Visible coolant routing where transparency is required
• Fabrication projects requiring precise, rigid tubing for neat internal routing

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Outer diameter: 14 mm
• Length: 50 cm
• Color / finish: Transparent, smooth surface
• Form: Rigid tube suitable for bending and polishing

How to use

Measure and mark the required length, then cut the tube squarely with a suitable tube cutter or fine saw to ensure a clean end face. Deburr and polish the cut ends before installing compression fittings or adapters. Heat and bend the PETG tube using a controlled heat source (heat gun or dedicated bending tool) to achieve precise angles; avoid overheating to prevent deformation. Insert the prepared tube fully into fittings and tighten to the manufacturer's recommended torque for a leak-resistant connection. Inspect the loop visually and pressure-test or run the pump with a temporary fill to check for leaks before powering other components.

Recommendations

Use coolant types and additives compatible with PETG and your fittings. When shaping the tube, apply heat evenly and use bending jigs for repeatable results. Perform a leak test after installation and periodically check for signs of dulling, stress cracking or deposits; replace the tube if integrity is compromised.
