Picking the Right Type of Keg Coupler and How To Install

While a clean beer line is important, there are other components that might play a strong part in ensuring the quality of the beer served.  One such component is the keg coupler. It is probably one of the most important instruments when it comes to transferring beer out of the keg into the line. It attaches to the keg valve and goes into the carbon dioxide gas line as well, forcing the air into the keg that ends up pushing the fresh beer out. So if you are inspired to serve your customers or yourself some of the freshest and most refreshing beer, it is important that the transfer of beer from the keg to the tap is flawless. This can take place only with the right keg coupler.

Different Types of Keg Couplers

Kegs from all around the world are made such that they attach only to specific couplers. The valves in these kegs are designed to be coupled specifically with couplers that are meant for those beers.

It is important to find the right coupler for the kegerator or kegs that you have stored in order to make the right fit and serve the best quality of beer possible. The D Type Coupler, used with US Sankey keg valves, is the most popular or common of keg couplers around. They serve a large range of beers and 95% of American beers. It would be smart to invest in just that coupler if the serving range is most of what you tend to use at your bar or at home. But you must make an assessment of your brands used before picking the keg coupler.

There a six major types of couplers that we offer and which are used globally, based on the origin of the beer that you are using:

Picking the Right Type of Keg Coupler and How To Install The A type keg coupler is best used with those kegs that have German as well as English beer brands. Common beers that can be attached are Guinness, Hoegaarden and Pimms.

Picking the Right Type of Keg Coupler and How To Install The D type coupler is used for imported American beers such as Goose Island and Blue Point. These keg couplers are not to be confused with the S type.

Picking the Right Type of Keg Coupler and How To Install The M type coupler is generally used for German beers that are not very commonly available in the market globally.

Picking the Right Type of Keg Coupler and How To Install The U type coupler usually works with European-type keg valves and is used for specific brands of beer such as Stella Artois, Leffe and Boddingtons.

Picking the Right Type of Keg Coupler and How To Install G type couplers are fitted where they serve European brands of beer. They are also called Grundy couplers. Everything from the Speckled Hen and Worthington to Grolsch can be served with these couplers.

How to Change a Keg Coupler

When installing the keg coupler, there are three things that need to be considered. The keg, the keg coupler and the carbon dioxide regulator are the three systems that need to be coupled and synchronised. Before starting the coupling process, the first thing to make sure is that the carbon dioxide regulator is attached to the carbon dioxide cylinder. The cylinder should be filled and the valve closed in order to ensure the correct installation of the coupler. The gas line must be attached to the “gas out” port on the regulator, while the other end of the gas line should be attached to the “gas in” port on the keg coupler. This ensures an airtight system on that end of the coupler. The “liquid out” port is where the beer line is attached to the keg coupler. The ends the first stage of the coupling process that attaches the carbon dioxide output with the coupler and thereon to the keg, which will then send beer through the line.

The next step is to connect the coupler with the keg itself. Before this step, make sure everything is shut and there is no leakage. The carbon dioxide cylinder valve must be switched off while the handle of the coupler should also be in the closed position. Then go ahead and find the locking neck of the kegerator and turn it to 25 degrees clockwise. After this, push the handle down into the keg valve and release it. This should mean that the coupler has been locked in place and securely attached.

Once the coupler is attached to the keg, you can switch the carbon dioxide cylinder on which will commence the gas pump into the keg. This will spell the time you should pull on the pressure relief valve to calibrate the gas pressure. Once you have it calibrated to your desired needs based on recommended serving pressure, the beer is ready to flow through the lines onto the bar counter.

The successful attachment of the keg coupler means that you are ready to serve your customers with the best quality of beer. Many breweries lose way in their process due to a lack of importance given to the mechanical components that go into serving the best beer. You might have a really good brew ready but you need to store and transfer it in the right manner to make the most out of it. Therefore, make sure you know everything about keg couplers when you have the best beer stored in your kegs so that you can deliver the best quality of beer that is possible.
