How can i tell whats the psi rate on a copper fitting?

What is the psi rating on a copper fitting?

My 3/8'' metal ball valve's lable says (WOG 600psi) so can i reach 600psi using "AIR"?

Don't worry im not gonna use that kind of pressure i just wanna know that i can trust my ball valve using high pressure,THANKS!!!!!

I believe WOG stand for Water Or Gas so yes theoretically you could. as to telling the PSI rating on copper fittings im not sure.

Usually, copper fittings up to 1" are rated to 500 PSI, fittings from 1.25" to 2" are rated to 400 PSI, and above that, they are rated to 300 PSI. Of course, you need to take into account what type of solder you use, and the rating on the copper pipe. For spudgun purposes and pressures, you should be fine no matter what.

However, do not buy copper DWV pipe or fittings. I personally do not know the strength of copper DWV, so unless someone else who knows better tells you, don't use this type of copper.

water or gas. Last time I checked, air was a gas. So yes, you can take it up to 600 psi if you must.

3/8 to 1/4 to 1/2? this does not make sense. You reduce from 3/8 to 1/4, and then increase from 1/4 to 1/2?

However, as a general rule, copper is pretty damn safe.
