JBJ solenoid regulators

[taz]

I've been using the manual sort of the CO2 regulator for about a year. Only about a month back I switch to the solenoid type. What puzzle me before I mount the new regulator to the tank, the pressure on the meter (manual solenoid) show at 950lb/in2. After I mount the new one the pressur shows 1150lb/in2. The second meter is at 3lb/in2. CO2 bubbles about 1 per sec. And today I saw the meter climbed to 1200lb/in2. How can this be possible? Meter faulty? Or is there any thing that I miss out during the adjustment?

the difference could be due to gauges manufacturing error.

the 50psi difference could be due to tank temperature. do monitor it a few more days and if the variation are similar daily, then there shouldn't be anything to worry about.

I have thought of replacing the main gauge of the new regulator with my old manual regulator. The thread size seems to be similar. Is it advisable to do so?

[tawauboy]

gauge and regulator are perform different functions.
so how can you replace your main gauge with your old regulator?

[taz]

Sorry for my lousy english. What I meant was can I use the gauge from the old regulator to replace the gauge on that new solenoid regulator. The thread size seems to be alike. Only thing I saw was that locktite (blue colour glue)in between the internal and external thread. Is it advisable? Would there be any foreseen problem? Thanks.

IMO, just leave it alone. You would not need so exact pressure reading. Just some sort of indication that there is still liquid CO2 in the cylinder will be good enough.

you should leave the gauges alone.
unless you can be sure that, after tinkering, the connections don't leak.
an inaccurate pressure reading is much better than a leaking co2 system, right?

Thanks for the advise guys. I guess I will leave it alone. Darn! I've never got anything right when comes to buying things.
