This compact, pocket-sized CO2 injector is the ideal tool for any home brewer using the BeerBox™! Press the trigger to pressurize the CO2 into the BeerBox™ and simply release the trigger to stop flow. Save remaining CO2 for later use. Made of high strength, glass-reinforced nylon, with brass valve internals.

Place a compatible 16 gram non-threaded CO2 cartridge (GAS019B) into the cartridge cup and screw the cup to the dispenser head. Next, connect the injector by threading it directly onto the valve stem (uses standard Schrader valve). You can easily control the flow of CO2 into the BeerBox™ by pressing the finger trigger, and then stop the gas flow by releasing the trigger. Any remaining CO2 left in the cartridge can be saved for later use.

Please note that this is designed specifically for the BeerBox and will not work with standard MFL Keg Disconnects.

Carbonating in your BeerBox: Transfer your homebrew from your fermentation vessel into the BeerBox™ via a clean and sanitized hose. Pour half of your priming sugar/water solution into one BeerBox™ and the balance into the other (for a 5 gallon batch). Our experience shows that it takes a good 30 days to reach an appropriate level of carbonation. There is no need for another vessel, going straight from fermentation to BeerBox™ works for naturally carbonating your homebrewed beer.

Transferring from a keg into your BeerBox: When you are ready to transfer from the keg (after carbonating) push some CO2 into BeerBox™ with injector then remove injector so you are ready to release pressure through the Schrader Valve. The Oxygen will rise to the top as the CO2 is heavier. You can alternatively tip the BeerBox™ up and release the oxygen out of the faucet now; then put BeerBox™ back on its feet.

Use Teflon pipe tape on the outside threads of the BeerBox™ faucet. Attach the hose using a 1/2″ clamp (not included) to prevent dripping. Attach the other end of the hose to a black, liquid out ball lock connector (with a second 1/2″ clamp). Then attach black connector to liquid-out side of the keg. (Alternatively you can place a growler filler in your tap and proceed as directed.) Be sure keg has pressure connected and BeerBox™ faucet is closed.

Now you can pull the BeerBox™ faucet forward to a locked open position and beer should begin to flow into the BeerBox™ from your keg. Depress the Schrader Valve to release pressure and allow the BeerBox™ to fill.

xIn both cases we recommend that you bleed off some pressure before serving!
