Carbonation / Line Cleaning Cap / Counter Pressure Bottle Filling Home Brew

This new model carbonation cap does everything that the carbonation cap does but this comes with several added features.
The post on this unique carbonation cap has been machined so it fits BOTH black and grey ball lock disconnects. It also includes a barbtail on the underside so you can attach some beer line to act as a dip tube. This allows the carbonation cap to be used in several different ways including:
1. Carbonate
2. Cleaning your beer lines
3. Use it to counter pressure bottle fill PET bottles
