HardTube Alphacool 16/11mm 90° 0.6m

The Alphacool HardTube 16/11mm 90° is a transparent borosilicate glass tube designed for liquid cooling systems. With a length of 0.6 m and a 16 mm outer diameter (11 mm inner diameter), this rigid tube provides a tidy, structured look and is compatible with Alphacool HardTube connectors. The tube withstands typical chemicals and temperature fluctuations used in PC water cooling and is intended for custom cooling loops where durability and appearance are important.

Advantages

Borosilicate glass offers high stability, chemical resistance and good thermal tolerance, making the HardTube resistant to common coolant additives and temperature changes. The rigid form improves internal cable/tube management and gives a clean, professional appearance compared with flexible PVC hoses. The 90° pre-bent shape simplifies routing in compact builds where bending the tube is not possible.

Suitable for

• Custom PC liquid cooling loops
• Systems requiring rigid, pre-bent tubing (90°)
• Builds using Alphacool HardTube connectors and fittings

How to use

Install the HardTube 16/11mm 90° by inserting it into compatible Alphacool HardTube connectors and secure according to the connector manufacturer’s instructions. Ensure connector seals and fittings match the 11 mm inner diameter. Before final assembly, check alignment and fit in your loop layout to avoid stress on joints. Use appropriate coolant and follow standard water-cooling maintenance procedures.

Recommendations

Use dedicated Alphacool HardTube connectors and follow pressure and temperature limits (maximum operating pressure 4 bar). Avoid attempting to bend the tube beyond the manufactured 90° shape and keep the tube free from sharp impacts to maintain integrity and appearance.
