Steam traps ODD bits etc. First stop ,last stop.
Used anti-seize compound in the well for heat transfer.
Perfect drop-in.

I would order from Supply House again!
Had a no heat situation on a hot water boiler. Thought it might be the thermostat/hot water control, so I ordered this control. The order arrived in good shape, and the product was excellent, but I diagnosed the problem to be an electrical problem instead. Return process was outstanding, just "order a return coupon" on the website, then print it and include when returning the item. Great process, well thought out.

It works but dial is hard to read
I used this to replace a hundred year old aquastat. While it works perfectly, the dial is hard to read. Past 140F, there are unlabeled dots but at this point they're actually fractions of 10F, unlike the rest of the dial. The stop nut will prevent you from turning the dial to see which dot is 150F so you have to take the entire cover off to find it. The adjustment nut requires a small flat-head screwdriver and a lot of force to get it started.
The Honeywell aquastat dials are easier to read.

Just what I was looking for
I needed to replace this unit on a Taylor water stove and was having trouble locating one. One major supplier had discontinued it. I was grateful to find exactly the right replacement from Pex Supply!
The adjustment nut was a bear to unloosen so definitely adjust it after you set the low temp kick in and before you install the unit in a tight spot.
