This optional accessory kit provides everything you need to get your BeerGun up and running! A liquid ball-lock disconnect, a 5ft length of hose for your CO2 line with 1/4" stainless flare connectors on each end, one stainless 1/4" disconnect and stainless clamp (for the 10ft beer hose that comes with the BeerGun), and a brass 1/4" NPT X 1/4" flare adapter for connecting to the CO2 valve on the BeerGun. Requires a spare CO2 port and shutoff valve on your regulator.
