This is a carbonator cap fitting threads on to PET soda bottles up to the 2 liter sizes and is compatible with ball lock keg "grey" quick disconnects. If you want to use a soda bottle as a growler to transport some of your kegged beer, squeeze out the air in the headspace and replace it with CO2 with some additional pressure to preserve perfect carbonation even if the bottle is only half full.
It's also a great way to quickly carbonate some beer that has been bulk aging to see how it's coming along. While a soda bottle doesn't match fashion with the fancier growlers at the party, at least your beer will be fully carbed.
