The G System keg coupler gets its name from the English developer Grundy. The valve face can be thought of as a circle with three sides cut off. Breweries such as Grolsch, Boddingtion’s, Caffrey’s, and Anchor Steam use it (50-liter kegs).
The G system beer keg coupler connects to the keg valve, “tapping” the keg. The gas line from the CO2 tank/regulator and the beer hose to the beer faucet attach to the coupler.
