Simply attach this device to the output gas post of your Keg then when the keg is full it will prevent further liquid exiting the gas post. This means you can literally set and forget and fill kegs automatically without the risk of kegs overflowing all over the floor.

This flow stopper includes:

  • 2 x duotight 8mm x 5/8 push in fittings
  • 1 x ball float
  • 1 x stainless spring
  • 2 x straight 8mm joiners
  • 1 x acrylic sight glass (with 5/8 male thread on either side)

If you want to pressure fill your keg and growler, then please use it with a Blowtie kit/spundling valve This will prevent foaming during pressure filling. This way your keg can be filled to the maximum and you don’t have to weigh the keg every time to confirm/check the same.
