Draught Beer Keg Couplers

Understanding Keg Couplers: Your Essential Guide to Draught Beer Dispensing

If you're new to the world of draught beer, one of the first things to understand is the critical role of a keg coupler. This small but essential device connects your keg to the tap system, facilitating the smooth flow of beer from keg to glass. By injecting gas into the keg, it pushes the beer out through the faucet, ensuring a perfect pour every time.

Choosing the Right Keg Coupler

Not all keg couplers are created equal, and many beer brands require specific types for compatibility. Here's a breakdown of the most common keg couplers and the brands they work with:

A-Type Coupler

The A-Type keg coupler is designed for some of the world's most iconic beer brands, including Guinness and popular craft beers like Camden Hells and Camden Pale Ale.
How to Connect:

  1. Lift the handle of the coupler fully so the base lies flat.
  2. Slide the coupler over the keg's sphere head and push it down until it clicks into place.

KeyKeg couplers are perfect for eco-friendly kegs often used by craft brewers. These kegs are made from recyclable plastic and are equipped with an inner bag that keeps beer fresh as gas compresses the liquid out. Additionally, the design allows easy venting for recycling.
Popular Use: These couplers are gaining traction with smaller breweries and keg sizes.
How to Connect:

  1. Lift the handle and align it over the sphere head.
  2. Rotate the outer teeth clockwise or anticlockwise until they grip the keg head.
  3. Press down to secure the connection.

Troubleshooting Keg Coupler Issues

Experiencing leaks? Here are some quick fixes:

  • Gas Leak from the Inlet:

    • Isolate the gas supply and inspect the gas pipe for damage or splits.
    • Replace faulty components as needed.

  • Beer Leak from the Outlet:

    • Check the product line for wear or damage.
    • Reconnect the coupler carefully without over-tightening.

Most leaks occur due to user errors, such as applying too much force during connection. By handling kegs and couplers gently, you can avoid these issues and maintain a flawless beer-dispensing experience.
