Keg Coupler - G System - Ergo Lever Handle



For confident performance, choose a keg coupler designed by the same manufacturer that supplies over 90% of the world's valves. The G System gets its name from the English developer, Grundy. The valve face can be thought of as a circle with three sides cut off. It is used by breweries such as Grolsch, Boddingtion’s, Caffrey’s and Anchor Steam (50 liter kegs). The keg coupler connects to the keg valve, "tapping" the keg. Both the gas line from the CO2 tank/regulator and the beer hose to the beer faucet attach to the coupler.
