Counterpressure Bottle FillerCounter pressure bottling allows you to transfer chilled, carbonated beer from a keg to a bottle with minimal foaming and CO2 loss. This CPF has three valves one to purge an empty beer bottle with CO2, one to control gas flow to push the beer, and one to control liquid flow of beer from keg to bottle. Includes complete instructions. Needed but not included is the tubing kit (#7207) which connects the filler to any draft system with 1 4 inch MFL
