XSPC RTL is a water based lubricant for bending PETG or Acrylic tubing.
RTL stops the bending rubber (bend cord, silicon insert) from getting stuck inside the tube after making a tight bend. This allows you can make more complex and tighter bends without the risk of snapping the insert and ruining the bend. After completing the bend, simply rinse the tube with warm water to remove the lubricant.
One 30ml bottle is enough for 1-2 builds and each 100ml bottle is enough for 3-6 builds.
How to use:
Apply a small amount of RTL to the inside of the tube
Insert the bending rubber and twist it to coat the rubber
Heat the tube and make the required bend
Pull the bending rubber out of the tube
Rinse the tube throughly with warm water to remove lubricant
