Beer and Cider Barrel Plugs for Each Stage of Production

Our high-quality wholesale silicone barrel bungs withstand high temperatures and multiple uses. We manufacture all our stoppers to fit standard barrels and offer several styles to accommodate each stage of the brewing and storage process.

Silicone Fermentation Bungs

Get proper ventilation while preventing oxidation and contaminants from ruining your brew. Our silicone fermentation bungs have a two-piece design that keeps the fermentation lock in the barrel until you’re ready to release the pressure. 

Solid Barrel Bung Plugs

Use these standard beer, cider, and seltzer barrel stoppers to plug oak barrels or tank lids. The tapered design creates a secure seal that keeps contaminants out and freshness in.

Solid Barrel Bungs with Top Grip Lip

We added a top-grip lip to our standard solid barrel bungs for easier insertion and removal. These beer barrel stoppers feature a tapered design for sealing almost any fermentation barrel or lid.

Standard Bungs & Stoppers with 3/8 Thru-Hole

Thru-hole style beer barrel bungs and stoppers are designed for use with airlock devices. Select from bungs with or without a top grip lip based on your needs.

Hollow Barrel Stoppers & Bungs

These cider, beer, and seltzer barrel bungs have a hollow center, making them more lightweight and flexible than our solid plugs.

Hollow Barrel Bungs with Top Grip Lip

The addition of a top grip lip makes these barrel bungs even easier to insert and remove than our standard style. This design also helps prevent the plug from falling into your barrel.
