    Americans need to expand their mind,
    and get hip to this stuff. Really.

    Well. I thought all Engine Builders and Plumbers knew this by now.

    I thought I did. The Teflon tape with some kinda blue strips in it are top shelf, bees knees, the sh*t. Blue.

    It is good tape. I wouldn't use it on n engine. JR

    Why not use thin wall PVC tubing with brad nails taped around the outside of the tubing?

    Not really EMT but thin wall water pipe with crimp fittings. Commonly available in galvanized, copper and stainless.
    All new installations are either press fit steel/cu/SS or PEX.

    Downside is that crimp fitting tool is crazy expensive, not sure if there is any low cost options under 1 grand today.

    I have a ****load of PEX tubing left over from building my house, thought of using it to run air lines. Though I probably should buy a better compressor first.

    I have a pex crimper, would be nice to use it again!

    I have to wonder if this would be a code violation in some places where conduit being used for air could be mistaken for conduit being used for electrical?

    Iron or copper works well for me. What's easier than sweating copper?

    My other thought is, how long before the welded seam starts to pin hole from moisture?

    Another home shop project that I have seen here in FINLAND

    Aignep Infinity makes it pretty easy installation, even the T-connectors incorporate internal "swan neck" to keep the water out of downlines.

    Not cheapest option but pretty straightforward to install.

    Like I said its not EMT conduit.
    Water pipe, crimp fittings, AFAIK rated for at least 16 bar and 110 cel temp. Dunno if it is officially rated for pressurized air, copper and SS are probably preferred if you ask the manufacturers.
    I'd probably use something not prone to rust but..

    And in here EMT is always aluminium or PVC pipe.
    And nobody does or knows how to "sweat" copper piping, old installations are high temp brazed but never sweated with tin based solder as "sweated" solder joints are not permitted in code.
