This duotight Flow stopper is great for filling kegs, keg to keg transfers, or fermenter to keg transfers.

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)

Note – For better results, we recommend using this product with the Blowtie kit. This blowtie spunding valve will help you pressure fill a keg meaning you can control the flow speed but also prevents foaming during the filling process particularly for carbonated beverages like beer.
