If you want to be able to read the temperature of your brew without lifting a lid, this is the answer! With the new Fermentap Weldless Thermometer, you can upgrade any existing kettle or keg to read temperature from the outside! Gone are the days of opening kettle lids to check wort or mash temperatures! 

The Fermentap Weldless Thermometer has a 2 inch probe, making it ideal for use in your Hot Liquor Tank or Boil Kettle. The 2 inch stem is much shorter than our 6 inch version, making this product a better suite for vessels with immersion heat exchangers. This Weldless Thermometer will work in Kettles & Kegs! The thermometer is our Fermentap Dial Thermometer, and features a hermetically sealed face, all stainless construction, and a fast response to temperature change!


  • Thermometer with 2" Probe and 3" Dial Face.
  • 2" probe is short enough to stay out of the way of Immersion Chillers or heat exchangers.
  • All Stainless Construction.
  • High Temperature Food Grade Silicone Gasket.
  • Will work great with Kettles & Kegs!
  • Requires a 1" hole to be drilled in the vessel for installation.
  • Replaces our WL113.

Great value and quality product
Loved the ease of install, doesn't leak at all. Nice big numbers and a short probe is perfect for BIAB.
The probe for the thermometer doesn't interfere too much with my brew bag since I do all grain BIAB.
Nice big numbers to see what temp I am at. It was calibrated correctly too, right out of the box.

Built a 20 gallon 5 kettle system
Our club built a 20 gallon 5 kettle system and used all weld-less fittings to cut cost. This worked out perfectly and is functioning wonderfully.

Perfect for Mash Tun
Leaked a little at first, but I found that all I needed was to put the silicon washer on the outside of the kettle for me. Worked great after that!

Perfect for my purposes
I needed a stubby thermometer for my CFC tower I built. While searching the catalog I found this in the weldless fitting area. It turned out to be $3.00 cheaper than the standard 2" probe dial thermometer. I'm very happy with this.

Great Quality But Needs Extra Silcone Washer
I love the quality of parts, but I kept getting a small leak. I had to add another washer to outside the kettle wall. The problem is they want you to drill a 1" hole in the kettle to accept the 1" thread and then put your kettle wall between the silicone washer and the 1 1/2" stainless steel flange. When you tighten the whole assembly the kettle wall doesn't form flat against the 1 1/2" stainless steel flange due to the curvature of the outside kettle wall.
