This stainless steel thermowell is your best option of monitoring temperatures in the 27L or 55L FermZilla. Since the thermowell installs into the lid, the thermowell will be well positioned in the middle of the fermenter to provide an accurate core temperature reading. On the bottom side of the FermZilla's lid you'll find several convenient drill locations already molded into the plastic. The thermowell is long enough to work with either size FermZilla (or other fermenters!), so if you need to cut the tube down a bit, we recommend using one of these Pipe Cutters. The FermZilla will still be pressurizable after installing the thermowell, just be careful to drill the hole no wider than needed to fit the Duotight bulkheads.

Duotight Bulkhead. All the others I looked at use a rubber stopper or something else.

If I install the Thermowell does it still holds the pressure ?
Carlos Chávez on Feb 17, 2020
BEST ANSWER: Kind of. The fitting for the thermowell does have an o-ring on the bottom, but on mine it didn't seal well. I plan on adding some silicone to seal it completely. Your mileage may vary.
Does this Thermowell interfere with the TempTwister? I assume they won't conflict, but I don't see any photos or documentation with both installed.
Alex McMillen on Jun 4, 2020
BEST ANSWER: No, it fits inside the coil of the Temp Twister. I have brewed several times with mine and it has performed well.
Has anyone been using this on beer? Any ill effects on flavor?
Brennan Doerr on Oct 2, 2020
BEST ANSWER: Been using this in a fermizilla and about 12 batches, haven't had any issues or any effect on flavor.

cheap and versitile
I use this with just a normal 5 gal bucket to monitor temperature. Its cheaper than the stopper/thermowell combo and seems to work just fine. Just drill/cut out a hole in the lid and you're good to go! I might try drilling a second hole in a stopper if I start getting contamination, but I've done a few batches this way with no problems.

Thermowell would not pass through bulkhead without reaming out threaded portion of bulkhead. Once that was done worked perfectly.

Thermowell is Great, Duotight Fitting okay
Very happy with the thermowell itself. Much longer than most others you can find, tip is domed as opposed to crimped, and the perfect size for my Inkbird temp probe. Also much cheaper than shorter crimped versions I saw on Amazon. On my 27L Fermzilla it reaches all the way down into the the collection container, I cut it to sit in the middle of the fermenter.

The duotight fitting is okay, does the job but there are a few issues.

1. It doesn't seem to properly lock against the stainless steel. When you push it in and then pull the little ring that should come down doesn't, and you can still pull it back out without having to compress the ring. I think it's because this fitting was designed to work with soft tubing, not stainless steel. It still holds the thermwell, and takes a good pull to get it back out, but could be better.

2. The fitting itself is plasic, but it comes with a metal nut to secure it to the lid, which stripped the plastic fitting immediatly. I noticed this before I started installing it, so I was being very careful to tighten it with very little force and a very short wrench, but it stripped the plastic threads immediatly, nothing a little glue can't fix, but I would advise to only hand tighten.
