1. Accurate Control: Tube bender can achieve accurate and tight bending at angles up to 180 degrees with index marking for the most accurate bending. Wide hook securely holds tubing. 2. Usage: When the two handles begin to meet, allows for easy fabrication of optimized bends of up to 180 while reducing work, better control and no crossing handles! 3. Clear Marks: The degree indicator wheel on the pipe bender is standard, and accurate bending is simply done by observing the pointer get the desired bending degree. The high contrast white markings on the green wheels provide excellent readability. 4. 180 Degree: The maximum bending Angle is 180 degrees, tubing bender also allows for bending in tight Spaces and takes up very little space due to its compact design. 5. Versatile Use: Pipe bender tool adopted 1/4in, 5/16in, 3/8in outer diameter design, suitable for easy bending of materials such as copper, stainless steel, steel. 1/4in 5/16in 3/8in 3 in 1 Pipe Bender 180 Degrees Aluminium Alloy Tubing Bending Tool for AC Refrigeration Repair (6 8 10mm) Item Type: Pipe Bender Size: . 6mm / 1/4in, 8mm / 5/16in, 10mm / 3/8in Support: Thin walled copper and aluminum tubes 7mm-1.5cm / 0.28-0.59in Color: As Shown Material: Metal+Plastic Package Contents: 1 * Pipe bending tool Only the above package content, other products are not included.
