I bought this from Kegkits.com. It took so long to be delivered, I bought one from kegconnection.com and it came immediately. Now I have 2. I would like to sell one ($40 shipped) or trade one for a co2 tank (good test date, please) plus $ if necessary, or trade for a ball lock keg. It is new and has a high side guage to 3000 and low side to 100 psig, with what looks like a 5/16 inch barb check valve. email if interested.
looks like this:
CO2 Beer Regulator, Double Gauge, 5/16 Check Valve, Chudnow
