Cleaning copper pipe and fittings for a solid solder joint, this 3/4" tubing brush with a wire handle scours the inside of a 3/4" copper fitting to bright, clean metal before soldering. A clean, oxide-free surface is essential for solder to flow and bond, and the stiff wire bristles scrub away the oxidation, dirt, and residue that cause cold joints and leaks. The wire handle gives a firm grip and reaches into the fitting socket, and the brush pairs with an outside pipe brush and flux for a proper sweat joint. It is a basic, must-have tool for any plumber soldering 3/4" copper.
