Does anybody have any recommendations for lead in air hose? I need a few actually. Only one has to be temperature relevant. I need to connect together the different sections of my system. Pump to coiled1/2" copper line cooler. Cooler to 3/4" copper condensation lines. Condensation lines to 30 gallon extra tank. Extra tank to original tank. Original tank to extra#2 tank 10 gallon. Tank 2 to dryer/filter. And the last hose is my working line that I connect to my gun. Right now it is 25ft 3/8" rubber hose with high flow fittings. Is that big enough for flow hose or should I run 1/2" for final hose?
I looked at pex last night but it doesn't seem very flexible and there lots of curves. And it isn't made for air line expressly. Amazon has some 1/2"hoses but the fittings either don't swivel for ease of installation or have too small ID. Thanks

This one needs solid copper tube or, if it must be flexible, a high temperature line with braided stainless covering. Unsheathed lines will just soften and burst, even the (supposed high temp 135C) lines.

Use copper tube with an adaptor at one end.

By now the air will have cooled somewhat. Braided line would be best or a high temp line.

Standard 10mm PVC will do for any of these, basically fixed lines.

I like a highly flexible hose that lays down on the floor and won't kink. Hybrid polymer, but there are others. 10mm here is fine.
