black pipe to copper - brass fittings?
I have forced hot water heating. There is black pipe in the basement and to some of the radiators. Over the years some of the black pipe to a couple radiators has been replaced with copper. I'm moving the black pipes to one radiator and would like to replace black with copper since that's easier for me to work with. It appears that in other locations, where copper has replaced black pipe, brass fittings were used to connect the black pipe to the copper pipe. They are threaded on the black end and sweat on the copper end. I can only find these types of fittings in copper. Am I identifing the fittings correctly as brass? Can I connect my new copper fittings directly to the black pipe?
The fittings I need are male adapter 1/2'' x 3/4'' and male adapter 1/2''
