Whatever you use, DON'T use PVC of any type for an airline. If it get's hit it can shatter and send shrapnel through out your shop.

If you are looking for ease of installation, you might want to consider something like this -

Just so there is no second thoughts


Don't use PVC

I've heard that the one of the "best" parts about PVC shrapnel is that it doesn't show up on xrays. ouch.

so... just so I understand.. PVC... bad?

:wink:

So you are saying the PVC is bad for air lines?

:wink::wink::tongue::tongue:

PVC is very bad for air lines. It gets brittle with age, then it blows, shrappnel all over. I have seen this happen in a machine shop. BAD NEWS.

LISTEN to everyone here. Do not ever use PVC (Pretty Vicious Cuts) for an air supply line. Do not even consider it as the end results can be dangerous if not deadly!

Besides all that, PVC for an AIRLINE, well I doubt that it would ever fly in the friendly skies.

OK OK OK i here you no pvc. Will go with black pipe in stead or the garage air kit.

Thanks

I work for an airline, and we never use PVC.

Boeing is working on a new composite jet, though, but I'm pretty sure it's not made with PVC...

Hope that helps.

Heavy weight copper is good for airlines --- but not the lower pressure rated water line grade from the home depot and Lowes. Suggest 3/4 inch schedule 40 supply or larger and then 1/2 inch drops to the connectors. Do not forget the valves on the branches so you can isolate the drops when you need to work on things. I like ball valves personally.

Pressure losses with high air flows to air tools robs effectiveness and air tools use high volumes of compressed air.

I'm not a fan of black pipe either. I put that in my garage and I have to fight rust all the time in the float valve in my water filter. I'd go with copper.

Could be wrong; but I don't think "schedule 40" is a rating designation for copper pipe??

There is small diameter plastic air line hose available that is safe to use. It is often used to connect pneumatic industrial equipment. Uses brass compression fittings and is easy to route through a shop. Look up your local pneumatic industrial supply companies, they all should carry it.
