The D system type keg is by far the most common in the United States. However, you may come across a different type of keg occasionally that requires a slightly different tapping process. Here’s a list of all the types of keg couplers and instructions on how to tap each.

  1. Ensure the keg coupler handle is in the upright (OFF) position.
  2. Align the two coupler lugs with the corresponding openings in the keg valve.
  3. Insert the keg coupler and turn clockwise to engage into position (about 90 degrees).
  4. Press the handle downward (ON) this will allow gas to enter the keg and beer to flow out of the keg.

For the Grundy “G” system keg coupler:
