I happend upon this cold plate and have no need for it. Its a six pass and appears to be brand new. I pulled out one of the yellow plugs to see if the fittings worked. It comes with the 4 fittings that are shown. $125 plus shipping (ive shipped one of these before and it fits into something like a $20 flat rate box for the cold plate).
Stout faucet $50 plus shipping
Silver regulator $20 plus shipping. Black one sold.
5 way co2 gas manifold with "old school" ball lock gas fittings and check valve fittings $40 plus shipping
Chrome faucet with handle extender that i cant get off, beat up but works fine Free if you buy $100 worth of this stuff from me
