Forum Title: Sweating copper near plumbers tape
I'm installing a tub filler in my bathroom reno. I think sweating the copper from the valve pictured below back toward the supply line will be the easiest way to make sure things line up. My questions are: 1. Do I need to use plumbers tape on the male copper threads screwed into the valve. Pic below. 2. Will sweating the copper fittings melt the plumbers tape to the point it no longer holds the seal.

solder the copper into the male before connecting to the valve.

And yes, you will need teflon tape or thread sealer

like Mr Matt suggested, sweat the adapter onto the pipe, let it cool then apply pipe dope to the threads and tighten with a wrench
