It looks like 1/4" NPT, but no dice. I wanting to run two regulaotrs in sequence so that I can go higher pressure on one than the other. So I need a way to thread in a barb for gas line rather than this hook to the tank. Anoyone know what size it is and where I can get a barb to male treaded fitting?
More details if it helps:
I have my tank in the closet next to the fridge with regulator 1 hooked to the tank. A gas line runs into the frige where I want to put the 2nd regulator. I’ll split the gas line from regulator 1 and run one at higher pressure (up to 30 PSI for force carbing) to one or more kegs, then run the other end of the T to the second micromatic regulator to lower the pressure to 5-15 PSI to other kegs for serving at lower pressure.
