Draught Beer Basics

all about couplers
A keg coupler connects the Carbon Dioxide gas line (CO2) to the keg. The compressed gas powers
the coupler to draw out the beer from the keg. Dierent countries use dierent style couplers, so it
is crucial to have the right coupler for the specic brand you are going to be dispensing.

Because of height constraints, you must use a Lo-
boy coupler for 1/6 barrels and slim 1/4 barrels.
Lo-boys are available in D and S Series, all other
series must use a standard keg coupler, therefore,
are only able to be used with short 1/4 barrels.
Please note - Macro brands like Miller and
Budweiser use D System keg couplers. Always
verify the coupler requirement for beers you wish
to dispense prior to purchasing.
