## Summary description

Acrylic replacement tube Alphacool 18565 for liquid computer cooling systems. Transparent tube with outer diameter 13 mm, thread diameter 10 mm and length 400 mm. Compatible with liquid coolant loops, it provides a visible coolant path and reliable flow. Suitable for custom water-cooling builds and component connections.

## Long description

Alphacool acrylic tube Ø13 mm, thread Ø10 mm, 400 mm is a transparent replacement tube designed for liquid computer cooling systems. The rigid acrylic construction provides a clear view of the coolant and a precise, straight channel for reliable fluid flow. With an outer diameter of 13 mm and a threaded end compatible with fittings that accept a 10 mm thread, this 400 mm tube is intended for custom water-cooling loops and component connections where a visible coolant path and neat routing are required.
Advantages
The acrylic material offers high transparency and dimensional stability, ensuring long-term clarity of the coolant path and consistent fit with compatible fittings. Its rigid form maintains straight runs without sagging and resists deformation under normal operating temperatures in PC cooling systems. The 400 mm length simplifies installation in mid- to full-size chassis where a single straight segment is preferred, and the threaded end enables secure mechanical connection without additional adhesives.
Suitable for
Custom PC water-cooling loops requiring visible tubing
Connections between reservoirs, pumps, radiators and water blocks
Systems where rigid, straight tubing segments are desired for aesthetic or routing reasons
Replacement of worn or damaged acrylic tubing in existing loops
Key specifications
Material: acrylic (rigid, transparent)
Outer diameter: 13 mm
Thread diameter: 10 mm
Length: 400 mm
Compatibility: intended for standard liquid cooling fittings that accept a 10 mm thread and 13 mm outer diameter tubing
How to use
Measure the distance between components to confirm that a 400 mm straight segment fits without stress. Cut the tube squarely if a shorter length is needed, deburr the inner and outer edges, and test fit the threaded end into the compatible fitting until secure. Ensure all connections are tightened according to the fitting manufacturer's torque recommendations and perform a leak test before normal operation. Avoid excessive bending or forcing the rigid tube into curved paths; use appropriate angled fittings or joints where direction changes are required.
Usage recommendations
Install in a clean environment and flush the loop after assembly to remove any debris from cutting. Use compatible coolant and fittings to prevent chemical incompatibility. Periodically inspect the tube and fittings for signs of wear, discoloration, or micro-leaks, and replace the tube if transparency diminishes or mechanical integrity is compromised.
