Description

We recently discovered this premium breathable silicone barrel bung and were immediately impressed with its robust design and features. To start with, the built in tabs really help make bung removal effortless. But where the bung really shines is in its two-piece design. When set to the open position, the bung acts as an airlock and allows the release of CO2 while maintaining a seal against oxygen coming in. This makes the bung ideal for alcoholic or malolactic fermentation in barrels or tanks. When fermentation is over and you no longer want the bung to "breathe" out, you just push the center cap into the bung to create a firm seal and the FE497 becomes a solid stopper!

Fits most 30 and 60 gallon barrels as well as the hole in the lid of most Variable Volume tanks!

tapers from 1 7/8" to 2 1/4" diameter

Great idea
These bungs work great and eliminate the need for bubblers on my still fermenting barrels.

Great for barrels
These are great for spirit/wine barrels 15G or larger. Easy to clean though they do get stained over time.

Can't live with out them, had other silicone bungs pop out during an unexpected secondary fermentation. well worth the price to prevent blown out end caps

Great Product
The Bungs fit great! It is always nice to know it will release any pressure if any fermentation takes place, no barrel explosion potential.

Wooden Cask, Averill House Vineyard
We gave these a shot on two cask, so easy to use. Not only do they fit great but interim tasting is easy with the center vent. Smacked it in with a mallet then popped the center piece in for a fabulous fit.

works great in brewery barrels
Perfect in 225L wine barrels and 200L liquor barrels - allows venting when needed.

Great bung that allows venting!
Not too much to be said about this bung, but it works great in the 225L wine barrels and 200L whiskey barrels we use in the brewery. The vent plug comes in extremely handy especially for finishing fermentations in the barrel, and doesn't seem to have an effect on oxygen permeability as far as I can tell.
