How to Tap a Keg With a Micro-Matic

Couplers allow gas to enter a keg through the gas line and beer to exit via the beer hose.

There are various MicroMatic keg taps available. Keg taps, or couplers, are different depending on what country and design the keg and beer are from. Most U.S. and Canadian keg and beer companies use the "D" system coupler for their kegs. European kegs typically use the "S" system keg coupler. The "A" system works mostly with German beer companies and British and Irish companies use the "G" or "U" design. The Twin Probe coupler system is used regionally by some microbrew companies. MicroMatic sells keg couplers for most variations of kegs.

1. Place the coupler handle into the upright and "Off" position.

2. Line up the side of the keg valve with the bottom of the coupler and insert the coupler onto the keg valve.

3. Attach the beer hose to the side nozzle on the coupler and the gas line to the top nozzle on the coupler.

4. Depress the coupler handle downward and into the "On" position to allow gas to enter the keg and beer to pass into the coupler

Twin Probe Coupler System
