OK cool thanks. Now my next purchase is going to be the needle/metering valve. I always get sooooo confused by model numbers with this CO2 stuff, probably why pre-build systems are so expensive lol.
I have been reading and reading about which valves, and I'm seeing good things about swagelok, and ideal, but I cannot seem to figure out if certain models will work for me or not? I just don't understand it. I'm seeing some valves for pretty cheap on e-bay, but just don't wanna buy it unless I know it'll work. Well any needle valve model within those top brands work for this? Or is there something specific I can look for?
