Connecting 1/2 copper to 3/4 pex with sweat
  • Running 3/4 pex and need to connect to 1/2 copper either with sweat or from 3/4 pex to male 1/2 pipe threads, but can not find such fitting?? Don't want to use brass reducer unless absolutely necessary. A 3/4 pex to 1/2 adapter would be nice!
  • Try this; take a 3/4" x 1/2" copper coupling, solder to your copper, then solder 3/4" copper by PEX adapter to the coupling.
