How to Make a Keg Bung
- 1). Purchase a #4 rubber stopper slightly larger than the bunghole it needs to fit from the local home brew shop. Purchase a tube of bunghole lube as well.
- 2). Lube the keg's bunghole using 1 tsp. vegetable oil.
- 3). Set the rubber bung's bottom over the bunghole.
- 4). Beat gently on the top of the rubber bung with the rubber mallet to secure it into the bunghole on the keg.
