Any reason I shouldn't or couldn't use it for a small 20' run?

Chris,
While many people use it, it is a no-no. It can fail catastrophically . It gets brittle as it ages. It is not to code. Better to use copper or there is a pvc that is made for air supply. For such a short run $ isn't that much of a issue so why not use the right stuff.

Thanks, Oh I just had some laying around and wondered if I could use it. I guess I'll just use it for some wiring and get some copper and sweat the joints or the right PVC.

Hey Chris,
Check out the local tractor/trailer parts supplier and ask for DOT approved Type B nylon air brake tubing. It is fiber reinforced and the 1/2" size is rated for 950# burst PSI. Working PSI is 150 PSI. Rated for -40 to 200 degrees F. It is easily run along the wall or strung across the rafters, bends easily around corners and with the push-to-connect fittings nothing could be simpler. It works for thousands of million/mile tractor/trailer rigs in all kinds of harsh conditions. I have used it in my shop for years. It is available in sizes up to .75".

Schoonie's got the right idea. Although I prefer the less costly Poly tubing. I get it at a Parker Hydraulic fitting and hose Co. Just watch the working pressure. As you go up in size, the WP goes down. I think 1/2 is 150psiWP, but 3/4 is only 90psiWP. The nylon will have higher WP.

I used copper and the nylon line. I have seen PVC after mass. It ain't pretty. You won't be upset with copper or steel. We never complain if the tool works ,we gripe like mad if it don't. This isn't a place to be cheap. I used 1/2 inch copper and ran the flex through walls and to the bench. That way I can move things without a lot of hassle.

All the air in my shop is run through high-pressure hose. It's not that expensive from most places that carry it, you can connect it however you like with manifolds and such, and if you change your mind you can just pull it off the walls and stick it up some other way.
