Does not fit Carboy
Stopper does not fit standard carboy. Would not recommend this product.

Response from Midwest Supplies
We've tested this thermowell and found it to be compatible with our 3, 5, 6, and 6.5 gallon glass carboys. There is a lot out there in terms of carboys, especially with older ones that have been around for decades, and some of those may have different opening sizes. Please contact us directly if the fit is poor on one of our carboys, and we'll be certain to help get things straightened out. We can do a return, otherwise.

Works Great
I was a little concerned from reading some of the reviews. While the included double hole stopper may be too small to easily fit some carboys, it is a perfect fit for the plastic Big Mouth Bubbler. I plan on switching from glass carboys over to the plastic BMB so I will be glad to use this. Another concern I had was if the temp probes that I am using for my BrewPi would fit and they do. I have the stainless sealed probes from china. I also use a STC1000 in another fermentation chamber. This probe also fits perfectly.

Very Useful with Johnson Control
A must have to control the temperature of your wort. Works great out of the box._x000D_Additionally, if you like to cook, this device along with a Johnson control and a croc-pot make for a great, affordable sous-vide system.

Necessary equipment
This is the second thermowell/stopper combo I've aquired. They're dead useful. Looked a little dingy coming out of the box, but cleaned up great. I'll be using to maintain temperature for a sour mash.

Must have accessory
Used it in conjunction with Johnson Temperature Controller and a Fermenting Heater. Keeps your sensor lead (thermostat wire) from coming in contact with your beer. Thus saving your brew from unwanted bacteria. Only four stars for quality because I had to file jagged edges at the opening of the tube that could have harmed the sensor lead. This only took a couple of seconds. Price could be a little less as well when you pay almost as much for the heat wrap. Otherwise more than pleased.

Needs some adjusting
Being able to control the heating element is crucial in the winter. I had to wrap it up in Cellophane to stay in, but it's been working fine since then.

Necessary to Have
This is something you must have to monitor the temp of your wert during the brewing process if you use a controller and a heating element of some sort. Be aware that stopper is only a size 6.5 at the max.

Does not fit Better Bottle, easy fix possible
This stopper does not fit well into the better bottle, but this can be easily fix by getting a drilled bung and inserting the metal thermowell into it. Also by doing the bung fix I was able to drill a second hole to insert a blow off tube. This thermowell is very useful in providing an accurate indication of temperature for the controller.

Imrpovise
The stopper was too small so I wrapped it a few times in plastic wrap and it works ok. For thirty dollars I expect more, and am taking off a star.

Can be made to work well
Its not hard to modify the stopper to increase the diameter. As some have mentioned use cellophane wrap. For this rice I'd have expected something better.

What is the inner diameter of the stainless tube? 1/4"?
Kevin C on Jan 7, 2016
BEST ANSWER: I asked them the same question because I wanted to know if the 12 inch long temperature censor would fit inside. slides like a perfect glove.. I love it. More over when I save for a big mouth plastic I'll to see if the rubber fits.. The Thermostar tm long length temp censor is one rch thinner than the 1/4 inch ID (inside diameter) of the stainless tube
what size stopper is this? What is the diameter of the bottom and top?
A shopper on Oct 25, 2017
BEST ANSWER: I can’t comment on the exact size, as I’m not near it now, but I know that it fits my 5 gallon glass carboy I bought from there perfectly Enter an answer to this question.
