What type of paste is best for threaded plumbing connections?
It doesn't really matter. The old oil based has worked forever, Teflon paste is a little cleaner. Either one will do the job. I use Teflon tape for most everything anymore. Clean and easy to use. Cheap also.

There are lots of ways to join C x C one can use compression unions, C x C unions , couplings, soldering ,brazing mechanical joints, flare x flare .
Absolutely YES and so does gas piping and heating applications . Your looking at it from the wrong end. .
There are actually 27 tapes used in plumbing depending on the application and medium being used
Left and right nipple and coupling / union / TP coupling
Teflon tape, which is wrapped around the threads, or plumber's putty, which is applied to the threads should be quite effecive at stopping the leak. These can be found at any …hardward store, and are inexpensive.
Any kind of non plastic piping will do (namely copper or galvanised for water and uPVC for Waste). Unless of course this cannot be done due to high theft of metallic piping.
There is NO coupling there is however a nipple or union to prevent electrolytic action from taking place between ferrous and non ferrous metals
what is a cross connection in plumbing
Cast iron pipe that is insulated.
Iron Pipe Size
Any pipe dope will work but Teflon tape is a lot cleaner.
