Installing copper for shop air. I have a few regulators and filters and am
wondering about the installation process.
My biggest concern torching in fittings near these "plastic"
regulators/filters. I was thinking I could sweat the near fitting then
attach it to the filter/regulator then sweat in the opposite side.
maybe I could get brass fittings for a thread to thread connection???
Either way I'm not sure of how to get these threaded in on a hard line
Any experienced replies in this would greatly help as my only exp in this is
an occasional hose bib or water pipe fix.
It has been my experience that the "ring" style compression fittings will
vibrate loose and leak if this is in a line that moves. On my hookah (gasoline
powered airless Gates compressor) I ended up having to go to flares.
It's easy, if you sweat the fitting on to at least 12" of pipe, thread the
stubs into you plastic stuff. Wrap a wet rag on the stub near the plastic
and sweat the assembly into your system with couplings. Another option
would be to put a tee at the place you want the regulator, sweat in a slip
to thread adapter, add the regulator after the system is plumbed. Don't
forget to put water legs at the compressor inlet to the system and before
$ .02, Allow for unions or other removable connections at each in-line
device. ( Solder/thread type unions are available. ) Use threaded filters,
regulators etc. as these will require service or replacement in time. Solder
in the fittings before attaching to 'plastic' devices and then screw them
into place using a quality sealant. Bleedable catch drops are a good idea
too, in-pipe condensation will occur as the air cools.
