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

Stopped My Bughole Right Up
Works as advertised, now nothing can get in or out of my bunghole. If you have a problem with things getting into your bunghole, I suggest you try these out!

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.

Does not fit the 23 liter Vadai barrel
This is a nice stopper. But it does not even come close to fitting the 23 liter Vadai barrel, as recommended by this site. No reflection on the quality of the product though.

Response from MoreFlavor
Too big or too small for 23L?
