Silicone Rubber Corks / Stoppers / Septa Gaskets

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. We are one of the very few manufacturers of silicone rubber corks, septa gasket, silicone rubber stoppers in India.
