5 pack Beer faucet plug/brush, sold by Kegconnection
This is a value pack containing 5 faucet brush/plug combo. These fit great on standard beer faucets. (***Note to Perlick faucet owners. I use these on my Perlick Faucets as well, but you have to modify them slightly because the hole is much smaller. What I do it take a box knife and just trip off the four little tap below the first Circle on the plug. This allows the first circle to sit flush with the Perlick. In addition you can still use it with standard faucets after making this modification because on standard faucets it will just go to the second circle to seal faucet.
