Stainless steel ball lock carbonation caps with 5/16″” barb.
PET Bottles as Growlers: These are generally intended to convert 1L and 2L bottles to growlers. Fill up a 1L or 2L PET bottle with your favorite homebrew. Put one of these on (purge the headspace by squeezing if you want to) and then pressurize for transport. This should help to reduce oxygen pickup and maintain carbonation levels.
Fine tune or rapidly carbonate beer: You can also use this cap to rapidly carbonate beer. Same process as for transport, just set your regulator to the proper pressure and shake or agitate the PET bottle to help introduce CO2. Or hook it up to CO2 and let it sit in you kegerator.
