You got yourself quite a bargain good sir. What the max working pressure of that model?
Max output pressure is 100 psi. It's more than enough for our use. I wouldn't have done it if it wasn't for Oldpunk and Bettatail. They introduced me and like everyone else into building CO2 regs. Like Oldpunk said, it's a hobby within a hobby.
No I haven't tested it yet. I know the regulator is working because Oldpunk already did the testing. Needle valve seemed very fine when I turned the vernier handle. I need to get another CO2 tank. I'll let you guys know how it goes.
