Barrel Bungs

Wholesale & Custom Silicone Barrel Bungs

Barrel bungs play a small but essential role in the making of wine, whiskey, beer, and other alcoholic beverages. Often made of cork, these stoppers are designed to plug barrels during fermentation, processing, and storage. While effective at sealing, cork does have disadvantages such as warping and being prone to mold. A better, more economical alternative is silicone barrel bungs. 


We Provide High-Grade Silicone Barrel Stoppers in Bulk

Ace Seal offers variety of silicone barrel bungs wholesale for wineries, distilleries, and breweries. Unlike corks, 100% FDA grade silicone is durable and does not stain, mold, or hold odors. Silicone barrel bungs are also reusable, making them a more cost-effective option. Whether you’re producing a fine chardonnay or bubbly spiked seltzer, we have the barrel stoppers you need.
