does anyone know how much a #20 aluminum co2 cylinder weighs full? i just got mine refilled again and it weighs about 29 pounds and I have around 675 psi reading on my gauges. I want to make shure im right about them shorting me before i go complaining tomarrow .

Depends on the cylinder. Next time, weight it before it's filled.

Your 675psi reading could be because the tank was recently filled. Wait until the temperature rises and you should see the pressure reading go up.

Is the cylinder cold? A CO2 tank with any liquid in it should be about 800-900 psi.

the cylinder is room temp which is around 69-70 degrees F i noticed there was something wrong when i started running out of co2 less than 3 weeks after it was filled. theres no way way that this cylinder is full weighing 29lbs.

have you checked for leaks??

i have checked for leaks. but i doubt it would leak that much the tare weight is arount 24 pounds. and i just got it filled today and thats the weight it was when i got home. i just want to make shure im correct about it not being filled before i go back to the store.

Sure tare weight was 24 pounds when empty? If so, they grossly underfilled the tank.

I have a 15# tank and it's pretty heavy even without CO2 so you may be right.
