Uniweld 70047 Swage Punch for 7/8-Inch OD Copper Tubing
Unwieldy 70047 Swage Punch for 7/8" 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.
