[Parameters] - Application: only for copper / aluminum tubes; applicable tube O. D. : 3/8"、1/2"; applicable tube wall thickness: 0. 6mm-2mm; bending radius of 10mm: 23mm (3/8"), bending radius of 12mm (1/2"): 35. 8mm; bending angle: 0~180°. [High Quality] - The tube bender is forged from high-quality aluminum alloy, which is light and durable. (NOTE: if the pipe wall thickness<0. 6mm, it will cause deformation of the tube. ) [2-in-1] - This tubing bender tool is a 2 in 1 tool and will fit 3/8’’、1/2’’ tubes, which is convenient for different size tube bending and save cost. [Humanized Design] - (1)The manual bender uses the principle of leverage, with which you can easily bend the tubes. (2)The round hole of the upper handle can test the size of the copper tube. (3)The bender is only about 1kg, light and portable. [Wide Applications] - This tubing bender is suitable for HVAC, air conditioning, and refrigerator pipe repairs.
