A system Keg Coupler 1/2″

Keg coupler is a key component of the draft beer system that connects beer and gas lines to the keg. Couplers are very specific and only fit the keg valve they are made for. A, D, G, M, S, U and Key systems are the major keg systems used across the world.
This coupler is designed for A system keg valves which works with notable German beers and hence is more commonly known as German slider style keg coupler.

What the Keg Coupler Does

Think of the keg coupler as a “key” and the valve of a keg as the “lock”. They can’t work without each other. The keg coupler attaches to the valve and to a CO2 compressed gas line. It allows the compressed air to enter the keg and push out the beer.

As a result of all of these components working together, you get a perfectly chilled and delicious draft beer in the comfort of your home.
