    ..specs for the steel air line...

    What are the specs for the steel air line found on the RT Classic? I need Internal Diameter, Outer Diameter, Max Operating Pressure and the type of steel used.

    are you looking to buy steel hardline?

      I'm far along in designing my own marker, unique mechanism, capabilities and all. At the moment I need to know the above information since the air lines will be integrated and it's a high pressure marker.

      Refer to this thread for further details: http://www.automags.org/forums/showt...82#post2573582

        that is way too long for me to read during lunch.

        anyways I have 1/4" ss hardline. it is rated to 10800 psi. I have 1/4" alum that is rated to 3000psi.

        both of these numbers I am tring to remember from their spec sheets. I might be off.
        1/4" OD
        ID varies.
        I use 316ss & I forget what kind of alum maybe 6-7000 series. it is expensive.

        wall thickness can vary depending on the pressure you want it to have. I run Scuba tanks off of it also, and an RT classic cannot out shoot/starve the line.

          Thanks, that SS hardline has a freaky high PSi rating! Looks like I'll have to talk to an engineering firm about my requirements. I'm looking at a SS hardline with about 0.185" OD and 0.079" ID. I also want to be able to sustain very high rates of fire, so the spec is open (and probably going) to change.

          A little off topic, but I have newfound respect for o-rings after reading up about the kinds of pressures they can seal against if seated correctly.
