Rigid tube bending lubricant XSPC RTL — 100 ml for hard‑tube PC watercooling bending

XSPC RTL rigid tube bending lubricant — 100 ml is formulated for manual bending of hard tubing used in PC watercooling loops. The clear lubricant reduces friction between the tube and the bending mandrel or forming tool, helping to prevent kinking, cracking and surface damage to acrylic or PETG tubes. Its compact 100 ml bottle is designed for hobbyists and system builders who need controlled application when forming tight or gradual bends in rigid coolant lines.

Advantages

The lubricant provides a low‑friction coating that helps tubes slide smoothly over mandrels and shaping tools, reducing the force needed to bend and minimizing stress on the material. It is a clear formulation that does not leave visible residue when applied correctly and assists in achieving consistent, smooth bends. The small bottle size is convenient for precision application and storage in a workshop environment.

Suitable for

• Bending acrylic hard tubing in custom PC watercooling loops
• Bending PETG rigid tubing for coolant runs with tight radii
• Hobbyist and professional system builders forming precise coolant lines

Key specifications

• Volume: 100 ml suitable for multiple small‑scale bending jobs
• Compatibility: formulated for hard tubing materials such as acrylic and PETG
• Function: reduces friction to prevent kinks, cracks and surface marks during bending
• Packaging: compact bottle designed for controlled application

How to use

Apply a small amount of the lubricant to the area of the tube that will contact the mandrel or bending tool before heating. Spread evenly along the intended bend line to ensure uniform lubrication. Heat the tube according to the tubing manufacturer's instructions until it becomes pliable, then bend slowly and steadily over the mandrel or shaping tool. Wipe away any excess lubricant from the tube surface after forming and allow the tube to cool and harden in the desired shape.

Usage recommendations

Use the lubricant sparingly — excess product can be wiped off with a lint‑free cloth. Follow safety and heating guidance provided by the tubing manufacturer and work in a well‑ventilated area. Test on a scrap tube if unsure about temperature settings or application amount to verify results before working on final components.
