Drilled Carboy Bung - Large
This universal bung is specifically designed to provide a superior seal due to its extended taper. It is made of rubber and features a larger top diameter of 2 3/8" and a smaller bottom diameter of 1 7/8". The top of the bung is equipped with a lip to prevent it from falling inside the carboy. Additionally, it has a hole that can be utilized for inserting an airlock. To ensure compatibility, it is recommended to measure the opening of your carboy before purchasing a bung.
