*by K***C on 6 October 2016*

Bought these [2pairs] for 3 half gallon glass jugs that I have for Homebrewing use. I usually brew 23L batches of beer, and put these into 19L Corny kegs. Therefore, sometimes i'll put 19L into the main fermenter and the remainder into smaller demi-johns or glass jugs with either a different dry-hop or different yeast. These bungs are good quality and come with a pre-drilled hole that is the right size for standard HB airlocks. I've also discovered that the spare bung [only needed 3, so bought 2 pairs] is very good when used for the 'Poor mans's Beergun'. Instead of a bung sliding into the bottle, this bung creates a good seal when pushed down on the bottle rim but makes for easier 'burping' and removal.
