& @ jeffkrol,
I tried to contact the people @DIYregulator.com to see if they would just tell me which pieces/package to buy. I haven't heard back from them so I decided to go to Holston Gas today to see if I could just buy the bits there and have them assemble. While there they said my regulator will "freez" and that co2 is corrosive due to being "wet." The being a corrosive gas goes against the research I've done. From what I understand it's mildly corrosive. Will this Harris GP702-125-346-A work, or should I start from scratch?
No it should not freeze and no it is not corrosive enough to effect anything. The GP uses neoprene diaphragms which Harris says should not be used with CO2. Being a used regulator there is a chance it is damaged or malfunctioned in some way but that would be the only thing that would keep you from using it. To properly test its function you must install a CGA-320 nut/nipple so you can connect it to the co2 bottle. If you search youtube there are several people that will walk you through the testing of the regulator.
