What is necessary for each tube size when bending?

Having an appropriate bender is essential for each tube size when bending because different tube sizes require specific bender types or adjustments to achieve the desired bend without damaging the material. Each bender is designed to accommodate certain diameters and wall thicknesses, ensuring that the bend is smooth and consistent. Using the correct bender prevents kinking, crushing, or wrinkling of the tube, which could compromise the structural integrity and functionality of the plumbing system. Therefore, being equipped with the right bender for the specific tube size is crucial for achieving precise and high-quality bends in plumbing applications.
