Rúrka Alphacool 18440

The Alphacool 18440 tube is a rigid cooling tube made from high-quality polymethyl methacrylate (PMMA). With a length of 80 cm and an outer diameter of 13 mm, it is intended for liquid cooling systems in custom PC builds and provides clear visibility of coolant flow while maintaining structural stability and transparency.

Advantages

Alphacool hard tubing offers a neat, structured appearance compared to standard PVC hoses. The PMMA material combines good transparency with durability. The system uses Alphacool HT connectors that form a sealed connection with the plexi tube and simplify assembly. The rigid tube can be bent to fit the loop layout when using an appropriate bending tool, eliminating the need for additional angled fittings in many layouts.

Suitable for

• Custom PC liquid cooling loops
• Visible coolant routes where transparency is required
• Systems that require rigid, tidy tubing instead of flexible hoses

How to use

Measure and cut the PMMA tube to the required length for your loop. If curved runs are needed, heat and bend the tube using a dedicated acrylic bending tool following the tool manufacturer's instructions to avoid cracking. Insert the cut ends into compatible Alphacool HT connectors until fully seated to achieve a sealed joint. Verify all connections and test the loop for leaks before powering the system.

Recommendations

Use only compatible Alphacool HT connectors and follow safe bending procedures for PMMA tubing. Avoid excessive localized heat and sharp bends. Perform a pressure or leak test after assembly and before system use.
