Get the Right Boat Bung Fit First Time

Sea Harvester Boat Bung Plugs are replacement screw-in bungs designed to suit compatible Sea Harvester bung bases. The coarse thread provides fast installation and is designed to be almost impossible to cross-thread, making replacement quick and straightforward.

To ensure the correct fit, measure the actual hole size in the bung base (measurement A), not the outside of the thread (measurement B). Replacement bungs are matched to their compatible base sizes for easy selection.
