Uniweld 70046 Swage Punch for 3/4-Inch OD Copper Tubing, Model: 70046
Unwieldy 70046 Swage Punch for 3/4 O.D. copper tubing. The swage punch is designed to enlarge one end of the copper tubing to make a connection without a fitting. Swaging method means one solder joint, not two, so it will take half the soldering or brazing time that fittings require.
