Stoppers & Bungs

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

Securely bung your full-size barrels with this locking bung. Great for tight bunging barrels while rolling them on their side, moving barrels from location to location, or simply for peace of mind that this bung will not accidently get knocked out of place. A stainless plate embedded in the silicone causes the bung to expand outward when tightened. This creates considerable pressure against the bung opening, ensuring a super solid seal. Use a crescent wrench or 1/2" driver to tighten the nut on top of the bung. Bottom of bung measures 1.5" and the top of the bung measures 2.5".

This stopper has two holes and we use it in the production of our #6.5 stopper thermowell. It features one 3/8" hole and one 1/4" hole. A racking tube or stainless tube can be inserted into the 1/4" hole with the aid of some lubrifilm, forming an airtight seal, and the 3/8" hole fits an airlock. Even after you wedge all this junk into it, it still fits a carboy neck! Also fits perfectly into a 1.5" tri-clamp ferrule, and the stopper's flange will ensure it doesn't fall in. Use this in any configuration you can think of, it'll fit: Airlocks, Thermowells, Racking Canes, and anything else you can imagine!
