2" Barrel Cap with Pin Valve, 8g CO2 Cartridges & Cartridge Holder

A Replacement 2 inch screw cap for beer pressure barrels, fitted with a brass valve CO2 injector system for use with 8gram CO2 Bulbs.

This also comes with 2 8g Food Grade CO2 cartridges

If you have bought a keg with a vent cap, then it lets air into your barrel as you take beer out the tap.  This can let in bacteria with the air that can turn your beer, cider or lager into vinegar. 

To prevent this from happening, this cap with pressure valve, will cause the keg barrel to hold co2 pressure from the secondary fermentation.  If this pressure becomes too low as you are pulling off your pints, then you can inject some more CO2.  This keeps the the pressure up, aiding an speed of pouring and a good head formation, as well as keeping the beer safe from bacterial infection.

This valve is fitted with a cartridge piercing pin, so can only be used with 8 gram CO2 cartridges. 

The cartridge holder holds the CO2 cartridge in place as the holder screws onto the valve and pushes the cartridge into the valve and onto the piercing pin.
