I got my MicroMatic dual primary hooked up to my freshly filled 20# tank.
As you can see there were a few leaks to work out, but I think I got them all. It's sitting under pressure now to be checked on in a few minutes.
First question: at the red arrow is a fitting that threads into the right side regulator. The left side regulator threads onto this fitting, mating with a flat face and washer, just like on the CO2 tank.
The fitting that threads into the right side regulator is left-hand thread. This means that as I try to tighten the nut from the left side regulator, I can watch the fitting unthread itself from the right side regulator! Is this normal?
Second question: my high side is reading 650psi at room temp. I thought it should be 800psi at room temp?
