co2 regulator/ pressure of co2

[singularity]

okay i am trying to add a pressure gauge (that goes to 2000psi) to my $30 co2 regulator but im not sure what th e pressure ratng on brass fittings is or what pressure of a co2 tank is. so what kind of fittings should i use? what is the pressure of a co2 tank at abot 75 F?

I would personally say go with galvanized steel. Thats probably your best bet for pressure rating. The smaller the diameter of the steel, the more pressure it can withstand, im not sure why but on all the charts ive seen thats how it seems. Anyway, good luck hope it works.

O yea, black iron might work as well, they use that on pressurized levels of steam, so that could work.

I would go with Brass only because I think the process of making it is a little bit more precise which would give you a better seal on the threads.(but really its not going to leak either way galvanised or brass) Galvanised would work and its a little bit cheaper. I like brass more becuase it looks cooler also.

I found this pressure chart by a quick search on google and it tells you the whole scale of CO2 pressure by temperature and amount full.

Mihlrad, the reason why smaller pipe and fittings can hold more psi is simple. Psi stands for pounds per square inch. The more area there is on the inside of a pipe, the more force there is on it. Smaller fittings have less area on the inside and so less force is acting on them, allowing them to hold more psi.
