Recently I got an Air Liquide Blueshield Series 45 Oxygen regulator at a garage sale for $10. I decided to retire it for my CO2 system. I had the inlet nipple replaced. I used Teflon tape and pipe dope to seal all the threads and soap test showed no leaks. However I did the following test which gives me grounds to worry.
1. I opened the tank and pressurized the reg (only HP side).
2. I closed the tank and left it for 12 hours. The needle didn't move even when I opened the tank valve again. So that was good.
3. I pressurized the reg again and opened the low side to 120 PSI.
4. I closed the valve on the tank and turned the reg's knob all the way to the left, so that gas was captured in LP chamber and the needle has stabilized at 100 PSI.
5. Then I unscrewed the reg with LP pressurize and left it sit. In about an hour, the LP side decreased to about 60 PSI and overnight pressure went down to almost 15 PSI.
Is my reg toasted?
