Perforated silicone plug 26/32mm with immersion sleeve

The Thermowell 26/32mm perforated silicone stopper is the perfect accessory for controlling the temperature at the heart of the fermenter.

It is used in the same way as the standard cap, which allows the insertion of a 9mm diameter bubbler.

However, it is equipped with a second hole opening onto a 39.4cm-long stainless steel thermowell.

This stem is removable. It can therefore be adjusted in height to suit multiple fermenters.

For temperature control, we recommend a fridge thermometer or an Inkbirdto regulate a fermentation fridge.
