Bungs/Stoppers


All of our stoppers are moulded. They are BPA-free, made out of Food Grade materials. They provide an air-tight seal to carboys, necessary for proper fermentation. They come with molded hole.

Each has a perfect consistency as they are all injection molded.

The quality is comparable to silicone stoppers. They stick perfectly to Glass and PET, even when they are wet.
