Kit κάμψης Alphacool 29126

The Alphacool 29126 bending kit provides a simple method to form smooth, accurate curves in HardTubes used in custom computer cooling loops. The kit includes a silicone insert that is placed inside the plexiglass tube before heating; the silicone's high heat resistance prevents the curved section from collapsing during bending. After the tube cools, the insert is removed, leaving a clean, stable curve. The kit is available for inner diameters of 10 mm, 12 mm and 13 mm, and comes in lengths of 30 cm for short tubes or 100 cm for longer runs.

Advantages

The silicone insert withstands high temperatures and supports the tube internally during bending, enabling consistent, collapse-free curves. The design is compatible with multiple inner diameters (10 mm, 12 mm, 13 mm) and two length options (30 cm and 100 cm), allowing flexibility for different loop layouts. The kit is blue and intended specifically for use with Alphacool HardTubes and plexiglass tubing.

Suitable for

• Bending plexiglass/HardTube tubing in custom PC water-cooling loops
• Creating short-radius curves in compact or small-form-factor builds
• Forming long bends in extended tubing runs

How to use

Insert the silicone mandrel into the plexiglass/HardTube tube so it fills the section you plan to bend. Heat the targeted area of the tube evenly until it becomes pliable, then bend to the desired angle while the silicone supports the internal wall to prevent buckling. Allow the tube to cool fully to set the curve, then pull the silicone insert out of the tube.

Recommendations

Use steady, even heat and avoid overheating any single point to prevent surface burning or deformation. Match the insert diameter to the tube inner diameter for best results. Handle heated tubes with appropriate tools and protective gloves.
