Alphacool 29144 Hard Tube Bending Kit for Custom Water Cooling – 12/13/16mm Mandrels, Silicone Inserts, Cutter, Chamfer Tool, Measuring Tape, Storage Case

Custom water cooling loops demand precise, kink-free bends, and freehand bending often leads to wasted tubing, leaks, or unsightly angles. The Alphacool 29144 Hard Tube Bending Kit removes that guesswork, giving you a complete set of tools to shape acrylic or PETG hard tubing with professional accuracy. Whether you're building your first loop or refining a showpiece, this kit ensures every bend is clean, consistent, and ready for leak-free assembly.

Who is it for

PC enthusiasts, modders, and system integrators who work with hard tubing in custom liquid cooling. It's ideal for anyone using 12mm, 13mm, or 16mm outer diameter tubes and needing reliable bends at 45°, 90°, or 180° without collapsing or deforming the tube.

Main features

• Three POM bending mandrels for 12mm, 13mm, and 16mm OD tubes – heat-resistant and smooth to prevent scratches.
• Three high-quality silicone inserts (clear/white) sized for each tube diameter, preventing kinks and flattening during bending.
• Supports common bending angles: 45°, 90°, and 180° for versatile loop routing.
• Includes a tube cutter for clean, square cuts and a chamfer tool to deburr edges for secure fitting compression.
• Measuring tape included for accurate length marking before cutting and bending.
• Durable plastic storage case keeps all components organized and protected when not in use.
• Tool color: black/silver; silicone inserts: clear/white.

Tips

Always insert the correct silicone insert fully into the tube before heating. Heat the tube evenly and slowly, rotating it over a heat gun, then bend it around the mandrel in one smooth motion. Allow the tube to cool completely before removing the insert to maintain the bend's shape.
