Do you use standard compression fittings with this tubing?
Or just the RapidAir fittings? I'll keep this in mind if I
need to redo the air plumbing. I'm sure it was easier to do
nylon, than iron.
When you have a pipe threader - everything can be solved
with threaded pipe :-) , and a quick trip to the hardware store.

Following the northern tool link, I found this "Rated up to
150 PSI and 70°F" That doesn't seem good. Is that a typo?
Other than that, it seems like a nice setup.
I used black iron pipe for my garage. (Not expensive, ~
$1.16/ft from the big box stores) A cheap threader from
Harbor Freight and a hacksaw is all you need plus a handful
of couplers and tees. Valves are readily available. All
the parts are available from your local hardware store or
big box store. Working Pressure capability is 217 PSI at
400F for 3/4" schedule 40 pipe. If you can't thread this
small diameter pipe, (3/4 or 1/2") then you probably don't
have the chops to work on cars ;) JMHO. My setup only took
me part of an afternoon to do.
Only problem with black iron is that you have to plan it out
in advance. Retrofitting black iron plumbing is harder (not
impossible) than using nylon.

I just installed my air system in my garage. PVC is
simply dangerous - shrapnel ripping through sheet rock 30'
away was enough to dissuade me. PVC will appear to be
fine until it brittles up with age and then lets loose on
you unexpectedly.
I have a friend who used PEX and his installation looks
great. The problem with PEX is that it degrades rapidly
when exposed to UV light. If you can keep it dark it will
work great. That means behind sheet rock or insulated.
I ended up going with two of these RapidAir kits from
Northern Tools plus a few other pieces for added drops.
System was simple to install, it does not leak, (when
installed correctly) and is easily modified. I have 6
total drops + hard connected retractable air hose and
sandblaster cabinet.

While it is only 1/2" OD (3/8" ID) I pulled a loop around
the perimeter of the garage effectively giving me 3/4"
delivery to my feeds. I installed 2 regulators, the
master one set at 135 PSI, and the 2nd one feeds a loop
set at 95 PSI with an auto oiler for air tools. The
system works well enough to drive my Sandblaster box at
100% duty cycle. I installed a Ingersoll Rand TSN45 2
stage 80 gal 5 HP compressor good for 16CFM at 135 PSI.
I am happy with the results.

Impact resistance is another problem. PVC under pressure
when I let something fly around was the final reason I
went ahead and used copper. I also sometimes pull on a
line enough to bend the copper, PVC wouldn't like that. I
wish I had done the main lines in 3/4 instead of 1/2 though.
