Have a keg of beer, but want to fill some bottles to take with you to the game, beach, or friend's house? The Beer Gun is a great way to fill bottles from a keg. Every part that comes into contact with your beer is stainless steel. This unit features a CO2 purge, which helps to prevent oxidation during filling. These features, coupled with a CO2 jacketing tube for bottle purging and ergonomic valve actuators, makes filling bottles faster, intuitive, more accurate, and easier than ever! Because the Bottle Filler Beer Gun doesn't require a pressurizing stopper, you can fill a bottle of any depth without buying different stem lengths or adding plastic hose extensions.
