What is everyone running for shop air lines? I bought 3/4 steel but decided against it. Im leaning towards RapidAir 1" alum. pipe but not sure I like the compression fitting idea. Any input?
I've done rapid air in our little farm shop, but my big shop (aka, our business) is all 1" and 3/4" Copper...a little overkill for most...

There are tons of people saying to do many different things over on Garage Journal. Black or galvanized steel is the most recommended, then copper, then rapid air, but never PVC.
I have enough 3/4" steel to do my entire garage, but have not had time to put it up. A friends dad has rapid air in his shop going on three years now and no issues and he always leaves it charged.
Hmm, Dont think I know of anyone running copper.
Black iron pipe is what used most over at garage journal. Next in line is PEX AL. It's very easy to work with. Buy a set of PEX crimpers and some fittings, and you're off.
Copper is expensive, and labor intensive...but I haven't had to mess with any of my shop air line for 16 years now.

I have experience in Pex and have the tools but the specs are worrisome.
PexAl
200 psi @73°F
160 psi @140°F
125 psi @ 180°F
Regular Pex ratings are lower yet. Also dealing with coiled pex is a pain and hard to make look nice and neat. IMO.
I'm doing my shop with just regular pex. 1 inch with 3/4 drops. And yes, the sticks are much easier to work wwith. Also, what PSI is your compressor. Most 2 stage are only 175PSI.
