I purchased a new oxygen tank from Aerox for my Aztec E Turbo, since the current 3HT tank just passed its 24-year life.
The new tank is coming in July, but they suggested I get the regulator overhauled in the meantime.
I'm trying to remove the regulator, but it isn't budging. There isn't any airflow when I switch the regulator to ON, so I assume that means it is fully depressurized.

Before I go out and buy a breaker bar for more leverage, any tips or suggestions on how to remove this thing?
