A Bung, Stopper or Cork is a truncated cylindrical or conical closure to seal a container such as bottle, tube or barrel. Unlike a lid, which encloses a container from outside without displacing the inner volume, a bung is partially inserted inside the container to act as a seal. These can be used for all types of glass bottles. These stoppers fit tightly to prevent chemical leaks.
