• Flow stopping device for easy filling of any keg or growler that has ball lock liquid and gas posts (like a 19l cornelius keg or any of our mini kegs or growlers with a ball lock spear).
• Simple operation with no need to watch as the flow stops automatically when the keg is full.
• Great for
  • home brewers to fill from fermenters to kegs
  • to fill small kegs from larger ones at home
  • taking with you to a brewery to get a quality fill to the brim without foaming or wastage, win/win for you and the venue!
