Designed to be mounted in your vise whether mounted on a bench, wall, or floor.( Works best when secured in a vice.) By turning the handle on the side of the tubing crimping tool, you can form the desired crimp on the end of the aluminum tubing or copper tubing. The detachable handle is specially designed for the user, allowing you to operate it more easily. Form a perfect bead on tubes so that rubber or silicone hose can be more securely clamped to them. Simply insert the end of the tubing between the dies and start cranking the turning handle. Give the wheel a quarter-turn with each full rotation of the tubing to gradually tighten the dies against the tubing. (Note: Always apply the bead before welding.)
