NOT happy--redoing my plumbed air system

[Al Willits]

Use pipe dope, leave the tape for plumbers, they get paid by the hour.
Been in pipe fitting for over 30 years now and I don't know a pipe fitter that uses tape on pipe.

Probably a reason for that...imho

If ya got more mess than a easy swipe with a rag, your using to much, pretty common though and I suppose to much is better than not enough...

btw they do use copper for nat and propane lines, code here anyway says ya can, does state how and where its to be mounted though.

Another tip, brass flare fittings normally don't need anything on them, the flare is what seals the fitting, not the threads, key word here is "flare" fittings,in fact anything on the flare can cause problems.

Most of all, when it comes to pipe or copper, I'd go with whatever your comfortable with.

Al....who likes pipe because you can hang stuff off it....

I was an apprentice sheet metal/pipe fitter for the Southern Pacific Railroad in the Sacramento CA repair shops for a couple of years, the only thing we used was a gray pipe dope on all fittings except high pressure hydraulic lines and hand honed flanges. I think this was before Teflon tape was available and prior to import pipe fittings.

I use teflon tape on the connectors that go on the gun. That is the only place, as several shops (some professional, we would loan each other specialized stuff), I have used, use different connectors.

Use a zero pressure coupler, then when not using the tool, I can release the pressure and have no leaks.
