Looking for a sight glass and thermometer for a keg kettle.

I am having two kegs converted to kettles and was wondering if anyone knew where I might be able to find reasonably priced sight glass and thermometer. The guy doing the conversion said that he doesnt stock those things but will weld them in if I provide it. Any help or direction would be nice. thank you. -shawn

Buy one 1/2" NPT SS pipe coupling and one 1/2" NPT SS half-coupling. Have the your welder install the full coupling low on the kettle just above the welded seam at the bottom. Tell him to make it flush on the inside and to protect the threads on both sides when doing the welding. It's nice to have it flush mounted on the inside for easy cleaning and you may want to use the available threads on the inside for a siphon tube. Then have him weld the half-coupling five inches or so above the lower coupling. This will be your thermometer port. You only need the threads on the outside for this. Again, it's best to have it flush mounted like the lower coupling.
Now then, if you insist on a sight tube, have him install another half coupling just above the bottom weld and offset 45 deg or so from the others to keep it out of the way of the thermometer and drain valve. Personally, I don't care to have a sight tube or thermometer on my boil kettle. It's just one more thing to get in the way when cleaning and I find it just as easy to measure the volume with the dipstick method. Actually, I don't use any sight tubes at all. You can easily plug any ports not in use, so it's better to have too many than not enough in this case.

McMaster (specialty parts), Bargain Fittings (sight glass and fittings), and Ebay (thermometers).

Here's what I have right now:

Two combo sightglass/thermometer kits, one is weldless ($38), the other needs to be welded ($33). (I can sell both as welded for a bit cheaper. These are all 1/4" NPT. The one on the right is just a sightglass with 3/8" NPT to the kettle ($18).

PM me if interested
