  • FS: Matheson Mini, Micro-Matic and Airgas regulators

    Well I hate to do it but I have a baby coming within the week, so my collection of regs has to be thinned out.

    For parts - Airgas Y12-N145B nickel plated dual stage - has usable 50 psi gauges & knob/cap, 2" nickel plated CGA nut and nipple plated by myself, I still have the sticker that goes over the shut off valve if you really want that. I did some testing and I'm pretty sure it has a blown seal inside, working pressure slowly rises during use. $30 plus shipping (will figure out shipping if someone actually buys this) CONUS - Cashiers check - Money order- PayPal


    Matheson 3852 - SOLD

    All parts on this build are new but were tested for about a month, rock solid, no leaks. Lightweight and compact, under 4lbs.
