This steel spring tubing bender is an elegant solution for bending and shaping thin walled tubing. Useful for making bends of up to 180 degrees without crimping or collapsing the pipe. Light weight and thin for easy storage, and portability. The hardened and tempered spring steel features a zinc plated finish. Great for soft copper, aluminum and other thin walled tubing. Made by General Tools & Instruments a quality supplier of Tools and hardware since 1922. For best results, be sure to buy a second smaller diameter bender and place it inside your pipe with a larger diameter tubing bender covering the exterior. Removal of the springs after bending is quick and easy with only minimal need for over bending.
