Alphacool HardTube 13/10mm 0.6m Transparent 4 bar

Alphacool HardTube 13/10mm 0.6m Transparent is a rigid cooling tube made of borosilicate glass for custom liquid-cooling loops. The tube measures 13mm outer diameter and 10mm inner diameter, with a total length of 0.6 m and a transparent finish that allows clear visibility of the coolant. It is rated for a maximum operating pressure of 4 bar and is compatible with Alphacool HardTube connectors and fittings designed for 13/10 mm tubing.

Advantages

Borosilicate glass offers high chemical resistance and dimensional stability under temperature fluctuations, providing a durable and clean appearance for water-cooling systems. Compared with flexible PVC hoses, this rigid HardTube improves system tidiness and enables a more structured layout. The transparent finish allows visual inspection of the coolant and the overall loop.

Suitable for

• Custom PC liquid-cooling loops
• Enthusiast and workstation systems requiring visible coolant routing
• Setups using Alphacool HardTube 13/10 mm connectors and fittings

How to use

Measure and plan the tubing route in your loop, taking into account the rigid nature of borosilicate HardTube and any required 90° angled pieces. Cut the tube to length using an appropriate glass cutting and polishing method or use pre-bent lengths/angles supplied by Alphacool. Install using compatible Alphacool HardTube connectors and tighten fittings to the manufacturer’s recommended torque. Fill the loop with the chosen coolant and perform pressure and leak tests before regular operation.

Recommendations

Handle the borosilicate HardTube with care during cutting, installation and maintenance to avoid chipping or cracking. Use fittings specified for 13/10 mm tubing and check seals and clamps during initial pressure testing. Avoid forcing bends — use pre-bent or angled glass pieces where required.
