Thermaltake Pacific DIY 16mm PETG Hard Tube Bending Kit

The Thermaltake Pacific DIY OD 16mm PETG Hard Tube Bending Kit is designed for PC builders who want to create professional-looking custom water cooling loops using rigid tubing. The kit bundles four 1000mm-long PETG tubes with a set of mandrels covering 45-degree, 90-degree, 180-degree, and 360-degree bends. These mandrels serve as internal supports that maintain the tube's circular cross-section during heating and bending, helping prevent crimps, kinks, and flat spots that can restrict coolant flow or compromise aesthetics.

PETG is a popular material choice for hard tube water cooling because it bends at lower temperatures than acrylic and is less prone to cracking or shattering. The 16mm outer diameter and 12mm inner diameter sizing is one of the most widely used standards in the custom cooling community, ensuring broad compatibility with compression fittings from Thermaltake and other manufacturers. While the kit provides the tubes and forming tools, builders will need to supply their own heat gun and tube cutter to complete the workflow. With enough tubing for a typical single-loop build plus extra for test bends, this kit gives water cooling newcomers and experienced builders alike the materials they need to achieve clean, precise runs.
