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.

If I install the Thermowell does it still holds the pressure ?
Carlos Chávez on Feb 17, 2020
BEST ANSWER: Mine didn’t seal at first. Then I watched the kegland YouTube video. Cutting the notch in the SS rod was the key! I scored it with the pipe cutter where it was supposed to fit in the duotight, then pushing it up to lock in the duotight sealed it off. Been solid at 1 bar.
Is there any way to buy only the 8mm duotight bulkhead? I need to be able to switch out thermowell between two lids.
Cayde Ellender on Nov 18, 2020
BEST ANSWER: Yes you can buy duotight fittings. Personally I bought multiple thermowells rather than move the thermowell back and forth. I didn't think the fittings would seal as well after a few swaps and can have multiple fermeneters going at the same time.
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: I use it with my All Rounder. Shouldn't affect your beer, if cleaned and sanitized, because it is made of stainless steel.

Bulkhead too short
I have the same problem as others. The threaded portion of the bulkhead is too short. I can't get it tight enough and it leaks.

Another fantastic product from down under
Outstanding quality. I'm running a Temp Twister, so I put a very gentle bend in the thermowell tube to separate it from the coils just a little.

Bulkhead is too short
The DuoTight bulkhead is too short to properly install into the lid. The nut that secures it in place constantly falls off. This becomes a major issue when you are expecting the fermentation vessel to be airtight for pressure fermentation.

It's an obvious issue, since Kegland now sells a Gen3 builkhead, which is longer and I would assume, solve this issue. But that fact that you can still buy the older, flawed version, is a bit disheartening.
The item they are selling is the Gen2 bulkhead.

This thermowell is much longer that the more expensive ones from other brands. You don't have to have a fermzilla to use it. You could insert it into any bung that is meant for a thermowell.

Threads Too Short - What A Bummer
This *could* be amazing, but sadly the duo tight bulkhead supplied is poorly designed. The bulkhead barely makes it’s way through the lid of the Fermzilla, leaving almost no thread for the nut to grab onto on the other side. This makes it exceptionally easy to strip the threads while tightening it in place. The threaded portion needs to be at least 1/4 inch longer. More Beer and KegLand really ought to stop selling this until they fix it. As it stands, I’ve ordered replacement bulkheads to replace stripped ones and I’m just crossing my fingers it won’t happen again.

Great idea, poor execution (hardware placement and design)
I purchased a thermowell along with a temp twister, blowtie and carb caps to use with my Fermzilla conical and do some temperature controlled pressure fermentation. I watched the Kegland installation videos on youtube then got to work. Unfortunately, what they didn't say is that you really can't install both the thermowell and temp twister. It's really one or the other because the thermowell is aligned with the temp twister's coil. An easy fix would have been for them to have the blow off that's in the center offset to the edge that way the thermowell can be installed at the center but it is what it is. The second issue was that within an hour, my thermowell's coupling was lose and wobbly, totally unable to hold pressure. This is because the metal nut had stripped the plastic threads off the duotight fitting. I had chamfered the hole in the lid as instructed but it didn't hold up at all. Now I have a useless thermowell and a hole in my Fermzilla lid. To say the least, I'm really bummed. I'm hoping to hollow out a large diameter bolt and solder it to the thermowell. I've already used a pipe bender to navigate it around the coil. Maybe it's work or maybe my fermenter will need a new lid.

Threads on the duotight connection are too short for the lock nut this causes the plastic threads to cross Thread I'm thinking about installing this connection on the inside this will provide more Thread for the lock nut

Good product but Duotight Thread Stripped
After a few weeks, I finally got to install my Thermowell. After drilling the hole and getting a precise fit for the duotight I noticed that the lid was too thick and the nut was not able to fully grab to the duotight. Unfortunately, this stripped the duotight fitting and I cannot get a tight seal on the lid. :(
I wish the threaded portion of the duiotight would be longer to increase the grip and prevent stripping.

Now I am stuck with a hole in my lid and will have to buy a replacement lid and a new duotight fitting and try installing this again. Luckily I had an extra fermenter, otherwise it would have been a brewers nightmare.

Thermowell is garbage
Strips threading after drilling through, should have additional threading to make this work properly. Garbage.
