A wine barrel bung, also called a stopper, is a plug used to close an opening in the barrel when making wine. This truncated conical closure is partially inserted into the container to form a seal that prevents the contents from spilling out and keeps outside contaminants from entering.

Ace Seal’s wine barrel bungs are made of the highest quality food-grade materials. We use only 100% FDA grade silicone in our bung manufacturing processes, and all our rubber wine barrel stoppers are engineered for premium sealing capabilities, durability, and longevity.
