6 QuestionsQ: Is this lead free? Also, will this work with steam?

Q: 1. How should I attach it to the 1 inch self made manifold? Where can I find the adapter (the tee I guess). I spent half of the night looking without success. 2. Its stick is 0.9 deep. What is the minimum depth it should go inside the manifold? Should it touch the bottom of the pipe (the manifold) or half of the pipe is enough? Thank you

I installed these right before the manifold (in my system between the pump and the distribution manifold). You have to make the tee for it. If you are using 1” pipe, just go to a local building supply (Lowes) and get a 1x1x1 tee. Splice the tee into your line and then solder on a ‘1” solder to 1” FPT’ fitting adapter onto the remaining tee. You then use a bushing (or a combination of bushings) to reduce the FPT to the ¼” that is needed. I was able to find a 1” MPT to ¼” FPT so it was only a single bushing. It does not need to be inside the manifold, you are getting pressure and temp so close to the actual manifold that you will see little difference.
We just reduced it down with a standard 1inch to ¾, then another standard fitting like a female into the ¾ to a half or something. I'm no pro but did build a 5 zone mixed down heat ring and have a few of these on it. Some on the hot side, some in my hot water recirc and one in the mixed down side and they all work well. The temp is picked up if its not exactly in the stream.
You need to add a 1 x 1 x 1/2 copper Tee to your manifold and then buy a 1/4 in FPT x 1/2 in bushing from your local plumbing-hydronic supply store. Its called a gauge bushing and they are very common for hydronic boiler installations. I don't know if Pex Supply carries them or not but they should along with their Tri-dicator gauges. Using this bushing and the Tee your gauge will be just the right depth inside your Tee for a good indication of temperature and pressure.
I have done the same thing. I'm assuming the manifold is copper. I needed to use a 1x1x1/2fpt bronze tee and then use a 1/2x1/4 bushing. This gave a connection that put the end of the gauge in the middle of the flow through the tee. Bronze tees are not cheap but copper tees are not thick enough to thread. Sweat the copper to the tee and then the bushing and gauge thread in. Hope this helps.
I simply put a tee in my manifold (I put one on the outflow and one on the return so I could see the temperature drop). I then put an adapter in the tee so that I could thread the gauge into the tee. I tried to size the nipple coming out of the tee and the adapter so that the end of the gauge was in the middle of the pipe. Seems to work well.
I bought the threaded adapter from either Menards or Home Depot in the Plumbing section. Look in the brass fitting. Screwed that adapter into a female thread sweat on tee into the system. The probe is suppose to go into the main pipe flow and not touch the wall of the opposite side.
Q: Is there a Tee to plum this in on the output of a water heater?

No. This should just be a threaded fitting. You will need a threaded fitting that slides into a 1/2" copper tee that comes off your water line. Nathan Nagaruk NJ Construction, LLC
You probably have to install a 1/2" x 1/4" copper by female bushing either on the branch or on the run of the tee and then screw in the gauge.
Yes use a 3/4 x 1/2 inch swt x NPT tee with bushing 1/2 to 1/4 inch for Tridicator. Eric EZ
Q: I am looking for the housing that the td 090 screws into. the gauge that I am replacing has a shorter probe and screws into some kind of spring loaded bushing. thanks

You need to buy a reducer or increaser at your local hardware store. It's probably a 3/8" or 1/4" female with a 1/2" or 3/4 male end. Make sure it's brass or copper! David Kelly Metal Solutions llc
It will screw into an standard ¼"npt female adapter . the gauge you are replacing may have a specific well housing that you are referring to. This gauge is temperature and pressure so it would not work if screwed into a dry well.
Q: do you have to set a temperature for this quage and if so where on the burner is it?
