Automatic Keg Filling Stopper

The Automatic Keg Filling Stopper for filling beer kegs or transferring beer between kegs.

Automatically cuts off the flow when the keg is full, as the ball is pushed upwards by the beer. A small drilled hole limits the filling pace.
This simple construction allows the brewer to multi-task while filling kegs.

5/8" BSP treading that fits many commercial keg couplers. Attach the Stopper to the gas side of the keg coupler.
To keep some headspace in the keg and avoid overfilling, the keg should be positioned at a slight angle during filling until the keg coupler have been disconnected. To avoid excessive foaming, make sure that the beer is cold and not over-carbonated.

Materials: Stainless Steel, plastic, teflon, rubber and silicone
Threading: 5/8" BSP (female) and 1/4" BSP (at the outlet)

May be disassembled for cleaning.

Keg coupler not included.
