## Long description

The Alphacool 18531 tube is a black PVC tube designed for liquid cooling systems in computers. It has a 1.3 cm diameter and a length of 100 cm, providing a flexible and durable conduit for coolant circulation. Manufactured by Alphacool, the tube is intended for use where a reliable, low-maintenance tubing solution is required to connect radiators, reservoirs, pumps and water blocks within a cooling loop.
Advantages
The tube's PVC construction offers resistance to kinking and good dimensional stability while remaining flexible enough for typical PC routing. Its black color provides a discreet appearance inside most builds and helps hide coolant coloring or minor residue. With a standard diameter and a 1 m length, the tube is suitable for straightforward installation without the need for custom cutting to short lengths in many typical builds.

Key specifications

 Inner/outer diameter: 1.3 cm (nominal diameter specified)
 Length: 100 cm
 Application: Liquid cooling for computers
How to use
Measure the required lengths in your cooling loop and cut the Alphacool 18531 tube to size using a sharp tube cutter to ensure a clean, square end. Slide appropriate compression fittings, clamps or barbed fittings onto the tube ends and secure them firmly to radiators, pumps, reservoirs or water blocks. Ensure fittings are compatible with the tube diameter and check connections for leaks after filling the loop. Route the tube to avoid sharp bends and contact with moving components.
Usage recommendations
Before final assembly, perform a leak test by filling the loop and running the pump outside the system or with powered-off components for several hours. Replace tubing if signs of hardening, cracking, or discoloration appear over time. Use compatible coolant types to avoid premature material degradation.
