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 listed below under "You Might Also Need".

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.

Works...Sort of...
This product works.. sort of. Basically the holes are slightly too big so there is not a perfect air tight seal. The best solution is to wrap the airlock/coolstix and thermowell with a few layers of plumbing tape to help close the gap. After using the plumbing tape I’ve had no issues.

CoolStix Stopper in Conjunction with a CoolStix works very well.
I have been very happy with the CoolStix in conjunction with a brew bag and frozen water bottles to enable me to brew lagers at controlled temperatures. Of course, this stopper is an integral part of this control system.
