Please note: This stopper was designed for use with the BrewBuilt CoolStix which has been discontinued. Two of the holes are for an airlock and thermowell, but the third 1/2" hole was intended for the CoolStix and you will need to plug it or utilize it how you see fit.
This #10 3-hole silicone stopper is used alongside the BrewBuilt CoolStix for Carboys. The holes are for a 1/2" CoolStix, an airlock, and a thermowell.
The holes measure 0.500", 0.413", & 0.375"
Compatible with Fermonsters and our Plastic PET Carboys listed below under "You Might Also Need".
