I have a mix of kegs in my brewery - and I can't tell them apart. Corny and Firestone, Coke and Pepsi, tall skinny kegs and short fat kegs, native ball-lock and pin-locks converted to ball lock.
This weekend I took apart four kegs to clean them and when I went to reassemble, the last liquid post on a Pepsi keg won't fit. I tried swapping around the posts in every conceivable combination, but I'm always left with one that won't fit.
I'm using two of the four for pressure fermentation right now, and they're holding pressure, so they must "fit" but is it possible I have a Firestone post on a Cornelius fitting? Or a Cornelius fitting on a Firestone post? I looked up the thread sizes and some of them are only 1/16" different, so I wonder if the dip tube o-ring is sealing even though the post is a sloppy fit?
Or maybe I have a liquid fitting on a gas post, or vice versa? Can I trust the "IN/OUT" marking stamped on the rubber? I understand some keg types have the same threads on liquid and gas, and others are different threads
Is there a step-by-step way for me to get the right posts back on the appropriate keg? Instead of just guess-and-check?
