Custom Barrel-Bung sizes

The standard sized Barrel-Bung currently uses a #6.5 rubber bung and is 14.5 inches (35.6 cm) long. This size is meant for a standard 3, 5, and 6 gallon glass carboy. I realize that some people may use larger glass demijons or smaller 1 gallon jugs. For a custom sized Barrel-Bung please email me at barrelbung at
