Tube bending lubricants make the job of inserting and removing the silicone bending cord from inside of the tubing. When bending rigid tube for a custom PC water cooling loop, inserts have to be used to prevent the tube from collapsing during the bend. These silicone inserts are very close to the same diameter as the inside diameter of the tube and can be difficult to insert and remove. Thankfully, special lubricants for the job are available. While other lubricants can be used, the bending lubricants at TITAN RIG are designed to be completely water soluble, meaning easy cleanup when your bending is done and no worries about residue being left in your loop.
