Description

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.

Please note: the stopper will fit all sizes of Fermonsters, however we only recommend using the 1/2″ CoolStix with the 3 & 6 gallon sizes. This is due to dimensional restrictions and cooling power limitations.
