U System Keg Coupler -Guinness Ireland

The U system Keg Coupler is specially designed to dispense these Creamy stouts like Guinness. It has 316 stainless steel probe and chrome plated brass body.

Guinness is a type of dry stout- A dark, top-fermented beer with a number of variations, including dry stout, oatmeal stout, milk stout, and imperial stout. It originated in the brewery of Arthur Guinness at St. James’s Gate, Dublin, Ireland and It is one of the most successful alcohol brands worldwide, brewed in almost 50 countries.

What the Keg Coupler Does

The keg coupler is a “key” for the keg valve which acts as a “lock” for the keg. They can’t work without each other. Each system keg coupler is compatible with a particular keg valve. Therefore, the S system keg coupler is compatible with only the S system valve. Visit our beer system listing for an expanded listing of beers that use the “S” system valve.

The keg coupler connects the gas line and the beer line, allowing the pressurized gas (CO2) to enter the keg. CO2 gas, on entering, pushes beer out of the keg. This beer travels through the beer line to the tap.

As a result, you get a perfectly chilled and delicious draft beer in the comfort of your home.
