So I just kegged an American Brown this past weekend. Everything went well with the transfer and I was, for the first time, able to do a closed transfer from my carboy (better bottle) into the beer out side of the keg.
I got everything cleaned up and suck the gas on the gas in side to give it a little pressure to seal the keg up before sticking it in the fridge to condition for a bit while I drink the other 3 kegs in there that are ready to go.
I have pin lock kegs and I put the gas disconnect on the post and can hear it leak. It doesn't leak when it's not on the post and it doesn't leak when on a post from another keg. The keg holds pressure too because I lifted the PRV pin and it hissed away.
I have 2 CO2 bottles with regulators on them so I grabbed the other one, set the pressure at 12.5PSI, connected another disconnect, connected it to the post and it too leaks.
So I have a keg that leaks when the gas is connected to it. I'm not sure what's leaking to be completely honest. I wiggled the disconnect around a bit and could not get it to seal up. I recently had beer in this keg too and it worked fine. I broke it down, cleaned/sanitized everything and replaced all the seals before adding the brown to it. The seals I used were the bulk ones you can get from McMaster Carr.
Anyone have any suggestions?
