#10 Silicone Stopper Thermowell

#10 Silicone Stopper Thermowell

In Stock
60 day no hassle return policy. Details

This carboy thermowell is used in conjunction with the Digital Controller, FE601A, FE610A, or FE602, to more accurately regulate internal temperature during fermentation. It is exceptionally useful during the start of fermentation when the lag between ambient temperature in the refrigerator and actual temperature in the carboy can vary greatly. Now you can keep your beer or wine within one degree of the set point on your digital controller. Designed to fit either 3, 5 or 6 gallon PLASTIC carboys or any other similarly sized opening hole. The unit comes with a 15" stainless steel thermowell and a #10 silicone stopper that will accommodate our sanitary filter, FIL90, as well. It can be used in any container with a stopper opening of this size where you need to accurately monitor and control liquid temperature.

Will not work with Johnson Temperature Controllers (FE600 or FE611) because the probes are too large.

does this work with inkbird temp controllers?
Dick Sheremeta on Sep 15, 2018
BEST ANSWER: Yes, I have used it with an ink bird controller and have no problems.
Is there a shorter version? I'm interested in this for the 3 gallon fermonster but it seems too long.
Bradley Jackson on Mar 13, 2019
BEST ANSWER: I haven't seen one that's shorter, but you can adjust this one by pulingl the tube upward through the stopper until the bottom is mid point in the fermenter.

Provides a perfect seal for my Fermonster. The thermowell is sized just right for my temperature probe, and allows for consistent temp control.

Great for Fermonster!
This is the absolute best stopper I have found for Feemonster lids! It’s soft and has ridges which hold it in place. My inkbird probe fits nicely and really helps regulate internal temp while fermenting or lagering.

Works great!
Installs firmly in my Fermonster lids. Long enough to reach 5 gallons of wort in a 7 gal fermentor. Well is wide enough to accommodate the temp sensor from my inkbird temp controller. Very satisfied with the results.

Snug fit
This stopper thermowell works perfect with my fermonster. No more taping the temperature probe to the side of the fermenter.

Works well and has a good seal
Works as described. The #10 stopper I used before would constantly slip out but this one does not. Also the thermowell makes temperature control easier. I used to have my probe taped to the side of the fermenter and required an adjustment to the temp set point to meet my desired fermentation temp.

Great stopper
This stopper has ridges on it, holds much better than the smooth sided one

Great quality.
Love the notches in the stopper. Keep it from popping out when wet with Starsan. Just the right length to locate the temp probe right in the middle of my 7 gallon Fermonsters.
