The HardTube project becomes a reality. Alphacool is going a whole new way and sets clear signs! The most commonly used method for water cooling is the normal PVC tubing - now Alphacool offers another method of water cooling. The HardTube variant brings even more order into the system which makes a much more structured impression. The Plexi-pipe can also be easily adapted to the system with the appropriate bending tool without having to use additional angle pieces. In order to install the pipes into the system, this must be cut to the appropriate length. For use with Alphacool fittings only.
