A keg coupler is a device that connects the gas and beer lines to your keg, allowing you to dispense the beer with a tap. Depending on where the beer comes from and how it is brewed, you will need a different type of keg coupler to tap it.
We will explain the six main types of keg couplers and what beers they fit. We will also provide some tips on how to use and maintain your keg couplers properly.
The six types of keg couplers are:
- D-type coupler: This is the most common type of coupler in North America, and it fits most American beers, such as Budweiser, Coors, Miller, PBR, Corona, and many more.
- U-type coupler: This type of coupler is mainly used for Irish beers, such as Guinness, Harp Lager, Smithwick's, and Magners Cider.
- G-type coupler: This type of coupler has a distinctive triangle shape and is used for some British, Dutch, and American beers, such as Anchor Steam, Boddingtons, Bass Pale Ale, and Newcastle Brown Ale.
- S-type coupler: This type of coupler fits European Sankey keg valves and is used for many European beers, such as Heineken, Amstel Light, Stella Artois, and Pilsner Urquell.
- A-type coupler: This type of coupler fits most German keg valves and is used for many German beers, such as Beck's, Bitburger Pilsner, Ayinger Celebrator, and Spaten Oktoberfest.
- M-type coupler: This type of coupler fits some German keg valves and is used for some German beers, such as Warsteiner Pilsner, Hacker-Pschorr Weisse, Paulaner Hefe-Weizen, and Hofbräu Original.
All these types of keg couplers have similar features and functions. They have a gas inlet on the side that connects to the CO2 or nitrogen tank via an air line.
They have a beer outlet on the top that connects to the faucet via a beer line. They have a locking mechanism that secures the coupler to the keg valve. And they have a back lever that engages or disengages the coupler with the valve.
To maintain your keg couplers properly, you need to follow these steps:
- Clean your couplers after each use with warm water and mild soap. Rinse them thoroughly and let them air dry.
- Sanitize your couplers before each use with a food-grade sanitizer. Follow the instructions on the label and rinse them well.
- Lubricate your couplers regularly with food-grade lubricant. Apply a thin layer on the moving parts and wipe off any excess.
- Replace any worn or damaged parts as soon as possible.
