Every time I turn on my CO2 tank, even just a little bit, I get a hissing air sound right at the connect shown in the picture. I have no idea as to anything to do with connections so if anyone could please let me know what I can do to stop this leak I would greatly appreciate it. I know for a fact the area shown is where the leak is due to some searching for the hissing. Thank you in advance for your help.
I had a similar problem, thought it was leaking from the same point. Turned out that I wasn't tightening it down on the bottle enough (actually the gasket wasn't thick enough) and CO2 was escaping through the back nut and hitting the reg at that point making it seem thats where it was leaking. just a thought
