Two Hole #6.5 Brewmaster Silicone Stopper
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!

Locking Silicone Bung for Barrel
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".
