When I put the new keg in the kegerator this week, I noticed I had lost all the pressure in the CO2 tank. It was fine before the keg kicked. Anyway, after getting the CO2 filled, I noticed a huge leak where the CO2 tank couples with the regulator. There’s a rubber ring on the regulator side. Nothing of that sort on the tank.
I was looking for a replacement piece on the site (hopefully not needing to replace the entire regulator) but I didn’t see any appropriate pieces in the site’s store (or on other sites). I also saw in another thread people talking about using washers between the CO2 & the regulator? I’ve never used these. It’s possible that I had one that fell out, but I don’t think I’ve ever used them.
