I like to add an o-ring in the inside to get a better seal
perfect for installing a thermowell to a bucket fermenter.
It could use better installation instructions. Works well after being installed
I've bought 3 of these - one for each fermenter - just too easy install and use. Put a quick hole in a lid and install the bulkhead. Use some star san to lube the tube and insert for correct fit...I cut the excess off with a tubing cutter and flare with a pair of needle nose pliers. Done. Sanitary. Quick. Cheap. Save the offcuts - you never know when you need a little Stainless Steel tubing to attach a blowoff line or with a duotight bulkhead.
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.
High quality materials; easy to install; worked flawlessly.
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.
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.
Works great with my fermzilla and inkbird temperature probe
Title says it all! I use this with the temp controller controlling glycol to the temp twister.
I like the option to add a thermowell. It's a better option for my needs than the brewmometer sticker that comes with the Fermzilla. The main issues I have with it are the location of the thermowell in the lid and the bulkhead seal. The thermowell is positioned just inside the cooling coil when you install both in the lid together. I'm not totally convinced the temp being read by the thermowell isn't being influenced by the temp of the cooling coil. The other issue is that the bulkhead is too short and it comes with a metal nut. The metal nut will barely thread onto the bulkhead and you have to put a lot of tension on the bulkhead and o-ring to catch enough threads to hold it in place. I'm not totally convinced it won't eventually break or leak under pressure.
Works great. I wish there wouldv'e been the recommendation to buy an additional lid with purchase or maybe include a plug to use with the Duotight fitting ($1.50 additional purchase). oOnce you drill the hole for it, you can't use the lid without it.
First things first - Much love to Kegland, their products are fantastic. My only complaint is the DuoTight through bulkhead connection. Can't count how many times I've fished a SS nut out of my beer...The SS nut is too short - meaning it goes up into the pressure cap too far to get a good hold of and it strips the plastic male threads of the DuoTight.I would much rather a plastic wingnut-type connection that I could hold onto and just snug up the tightness and a longer male threaded section to verify the threads are synced before tightening.Instead, I have to make a choice - use a wrench under the cap (that really doesn't fit in the hole where the nut sits under the pressure cap either) and tighten praying not to strip the plastic DuoTight threads ORTry to hold the nut with my fingers and tighten the DuoTight fitting from above and pray the threads are lined up just right so the SS nut doesn't eat the plastic threads and you guessed it - Strip the fitting.
Highly recommended quick shipping reasonable pricing clear communications would not hesitate by again
It took me a bit to get the lock nut tight and leak free, however once I did it works like a charm.
I wanted to be able to monitor wort temp more accurately and this is the very thing. Easy to fit.
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.
Does what its supposed to.
Thermowell would not pass through bulkhead without reaming out threaded portion of bulkhead. Once that was done worked perfectly.
I get a true temperature reading for control of my fermentation refrigerator. Thank you
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.
I'm having the same issues that others have had for a few years now. With newer generations of fermzilla, you're able to purchase the thermowell with a bulkhea that has a longer stem. Can you buy these newer bulkhead generations individually?
Look into KL14595. Should be gen 4 fitting with 38mm shank you’re looking for.
Is there any way to buy only the 8mm duotight bulkhead? I need to be able to switch out thermowell between two lids.
Yes you can buy just the bulkheads but for $6 more you don't have to pull the thermowell out - ever. Just try to buy a SS tube for that...
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.
Yes there are multiple sizes. I bought an extra since I stripped my first one.
Has anyone been using this on beer? Any ill effects on flavor?
These are the best I’ve seen. I have two of them and use them with my two Speidel fermenters. They have improved my Pilsners and lagered ales by giving me the internal fermenter temp which compliments the external freezer temperature. I use an Inkbird to control the freezer and an Engbird thermometer probe inside the thermowell.
Been using these for over a year - no ill effects at all - scrub it and sanitize between uses. I use these on a 3 gallon and 6 gallon ported Fermonsters and a Big Mouth Bubbler.
Haven't had any issues with beer. This thing is no different than any other thermowell you'd buy.
I use it with my All Rounder. Shouldn't affect your beer if cleaned and sanitized because it is made of stainless steel.
Been using this in a fermizilla and about 12 batches haven't had any issues or any effect on flavor.
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.
It doesn't interfere per se. You do have to pay attention to which holes you drill out for the Temp Twister vs the thermowell. The bulkheads are different sizes. Also the thermowell is positioned to sit just inside the coil. It seems to work ok but I do see the potential for your temp probe to get a bad reading because it's so close to the cooling coil.
Work together just fine. Close but no contact
No . Two separate pieces. You can put it in the middle
Nope - i have both installed on mine and fits very nicely with the temp coils
I have both installed and they fit together at least in theory. In practice once installed they're pretty close to one another and the temp twister will cool the thermowell before it has a chance to really cool the rest of the batch of fermenting wort. I experimented with how far to plunge the probe down the well to balance the impact.
Not really. You definitely have to plan out what holes the temp twister is going through before you drill out or it definitely will. Also the thermowell duotight if very delicate since you only grab the last few threads. If you bump it wrong it will strip out. The thermowell has to be run inside the temp twister.
Don't know what a temp twister is. I have 6 of these twells installed: 4 in glass carboy orange vinyl tops (thermometer port) 1 in the top center of a conical fermenter cap as a secondary thermowell and 1 in a tall fermenting bucket. They accommodate waterproof temp controller probes (10k type) and waterproof 1-wire temperature probes attached to my brew cave monitoring system. The thermo wells stay aseptic and dry. I just use waterproof sensors everywhere< and the 6mm id of these wells will handle them
It might. I'd grab an extra lid just in case it does. I'd grab an extra duotight fitting as well. I've busted two of em one cross threaded and another busted trying to get the thermowell through. It helps to heat up the tip of the thermowell when pushing it through the fitting.
No it fits inside the coil of the Temp Twister. I have brewed several times with mine and it has performed well.
