The Blichmann BeerGun accessory kit includes everything you need to get your BeerGun filler connected to a standard ball lock keg. It comes with a ball lock liquid disconnect, a liquid swivel nut set, a 5' length of CO2 tubing with 1/4" stainless flare connectors on each end, a stainless clamp, and a brass 1/4" NPT x 1/4" flare adaptor for connecting to the CO2 valve on the BeerGun.
All that is needed in addition are a spare CO2 port and shutoff valve on your regulator. We recommend either a Wye fitting and two shutoff valves with checks, or a 2-way manifold hooked up to your regulator. With these, you will be filling from the keg in no time, with no worries or hassles!
