HardTube Alphacool 16/11mm 0,4 m trasparente

The Alphacool HardTube 16/11mm 0.4 m Transparent is a rigid borosilicate glass tube for liquid cooling systems. With a 16 mm outer diameter and 11 mm inner diameter, this 0.4 m long tube is compatible with Alphacool HardTube connectors and is designed to withstand common chemicals and temperature fluctuations encountered in cooling loops. Its transparent finish provides a neat, structured appearance inside a PC cooling system while offering mechanical stability and reliable performance with a maximum operating pressure of 4 bar.

Advantages

Borosilicate glass provides high chemical resistance and dimensional stability across temperature changes, reducing the risk of deformation or degradation over time. The rigid construction improves system tidiness compared with PVC hoses and creates a consistent, clear visual result. The 16/11 mm dimensions match standard Alphacool HardTube fittings, ensuring secure connections and straightforward integration into existing hardline setups.

Suitable for

• Custom PC liquid cooling loops requiring rigid tubing
• Systems needing chemically resistant and temperature-stable tubing
• Builds where a transparent, structured appearance is desired
• Setups using Alphacool HardTube connectors (16 mm outer diameter fittings)

How to use

Measure and cut the HardTube to the required length if shorter sections are needed, using tools recommended for glass tubing to achieve a clean edge. Install the tube into compatible Alphacool HardTube fittings and secure according to the fitting manufacturer’s instructions, ensuring proper sealing and alignment. Avoid bending or forcefully deforming the tube; use angled or pre-bent glass pieces for directional changes. Perform a pressure or leak test at up to the system’s operating pressure (not exceeding the specified 4 bar) before normal operation.

Recommendations

Handle borosilicate glass tubes with care during cutting, installation and maintenance. Use appropriate protective equipment and ensure connections are tight and compatible. For directional changes use pre-angled glass segments rather than attempting to bend the tube. Follow the cooling loop and fitting manufacturer's guidelines for assembly and leak testing.
