Alphacool HardTube 13/10mm 0,4m transparentná 4 bar

The Alphacool HardTube 13/10mm 0.4m Transparent is a borosilicate glass tube designed for custom liquid cooling systems. With a 13 mm outer diameter, 10 mm inner diameter and a length of 0.4 m, it provides a rigid, chemically resistant channel for coolant flows and is compatible with Alphacool HardTube connectors. The tube is rated for a maximum operating pressure of 4 bar and is suitable for tidy, structured PC water-cooling builds.

Advantages

Borosilicate glass offers high dimensional stability, resistance to most chemicals and temperature fluctuations, and a clear, durable appearance. Compared with flexible PVC hoses, this HardTube increases system neatness and gives a more structured, professional layout. The tube is lightweight and intended for use with Alphacool 13/10mm fittings.

Suitable for

• Custom PC liquid cooling loops
• Systems requiring rigid, visible coolant tubing
• Builds using Alphacool HardTube 13/10mm connectors
• Environments where chemical and thermal resistance is needed

How to use

Measure and plan the loop layout before installation, selecting appropriate Alphacool 13/10mm fittings and angled tubes where required. Cut or choose preformed lengths and handle the borosilicate tube carefully to avoid impact damage. Insert the tube into compatible HardTube connectors according to the connector manufacturer’s instructions and check seals. Fill the loop with coolant and perform leak testing at up to the specified 4 bar limit before regular operation.

Recommendations

Use this tube with matching Alphacool 13/10mm fittings and preformed angle pieces when possible. Avoid striking or bending the glass; use appropriate supports and clamps to prevent stress. Perform a controlled pressure/leak test after assembly and follow coolant manufacturer guidance to prevent chemical interactions over long-term use.
