Drilled Carboy Bung - Medium
This bung is specifically designed to fit plastic carboys and has a tapered shape to ensure a tight fit. A tapered lip helps ensure it stays firmly in place. It is compatible with most plastic carboys that have a capacity of 3, 5, 6, or 6.5 gallons. Before using the bung, it is important to measure the opening of your carboy to ensure it falls within the dimensions of 2 3/8" x 1 11/16".
