Hi all,

I bought a Matheson 8-320 CO2 regulator on ebay and i'm having some trouble identifying the connectors coming out of it. I've read online that it can either have the 1/4" NPT connector or a weirdly threaded monstrosity that requires an adapter of some kind. Is mine 1/4" NPT or the other?

The pictures are as follows:

1) the regulator itself
2) the part that goes to the tank - what is the white plastic stuff capped inside? is that a stopper that I have to remove?
3)the low pressure output side - is this 1/4" npt?
4)a valve that came with it that was in the low pressure output - I removed it.

Help me plantedtank forum, you are my only hope.

Thanks buddy, I'm glad the outlet is 1/4" npt, that makes things easier for finding parts. Any recommendations of companies that sell pipe fittings online? I'm not very mechanically inclined, what are te specific names of the parts? What will convert 1/4" to 1/8"? I assume I'll need a 45 degree elbow from the outlet to the solenoid if I want it straight for my jbj bubble counter, right?
