No pipe dope is to be used on the brass seats they will seat dry.
NO, nope, No way
pipe dope and teflon tape
NO but you will need some type of sealent OR braze or soldering
Teflon tape, Hercules Pro dope, pipe joint compound and quick wick , Pipe joint compound without quick quick wick , Blue block ,Teflon paste
when joining to lengths of black steel it is necessary to use either Teflon tape or pipe dope, also called leak lock, this is not to seal the joint per say but the tape and doping act as a lubricant on the threads of the joint allowing for the pipe to be turned together tighter also the dope will dry and become a sealant
Grooved method? Threads on the end of the pipe? There is no tube or pipe in copper with threads. You can end a copper pipe with a connection that is threaded to accept steel pipe.
You will want to put a length of copper into the fitting and solder it before you put it on the galvanised so that you don't cook out the pipe dope. >>they also could have soldiered on a flange on copper and thread on galvanized pipe.would have been another choice
Teflon Pipe Dope. Guaranteed I would have to either weld or braze the piping together
If you are screwing in -- yes -- If not -- you do not use pipe dope
If it is leaking at a fitting, it is either a bad flare or it isn't tight enough. Gas or flare fittings should be put together dry, Do no use pipe dope because this can cause a leak between the mating surfaces. If it is in the line itself, either replace the line or cut it, flare the ends and put a fitting in.
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.
no
Pipe dope and/or teflon tape
