Duotight Flow Stopper - Automatic Keg Filler

Sold out

This really handy device is great for filling kegs, keg to keg transfers or fermenter to keg transfers.

Fantastic for use with Fermentasaurus or other pressurisable fermenters.

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.

For even better results we recommend this product to be used with the BlowTie Kit.  This blowtie spunding valve will also enable to to apply head pressure to the keg meaning you can control the flow speed but also reduce the foam generated in the filling process particularly for carbonated beverages like beer.
