Foam On Beer Dectector (FOB)

FOBs are installed in long draw draft beer systems to reduce beer waste and increase profits for the business.

This works by stopping the beer flow immediately when the keg empties, the beer line will remain full of beer instead of filling with foam. Meaning you can reattach a keg and keep dispensing without that wastage of foamy beer in the line that you would have to replace with beer and purge the system.
 
NEW Design
- As the duotight fittings are becoming extremly popular with many of the commercial beer plumbers we have made the barbs on this FOB duotight compatible.  So now you can attach your 3/8inch (9.5mm Evabarrier beer line) directly onto this FOB without the need for clamps.  Simply use duotight joiners and you can just push fit the line for a reliable seal.
