Q: Is this for a specific type of Corny, e.g., ball-lock vs. pin-lock, or are all Corny keg lids the same? Guaranteed to fit? (I have a lid with carbonating stone & hose and threw money away because it leaks like a sieve).
A: this will work on most ball lock and pin lock kegs. If the keg on hand is a Firestone 'racetrack' keg that has the flat-sided lids, this would not work on those kegs
