I couldn't find a thru wall housing for a 1/4"" Sensor that I was sent with a new controller. I finally called your tech support. They steared me to this one. It came in a timely. Shipping was a flat rate that wasn't outrageous. Everything worked well. I did have to make the hole in the tub bigger. They tell you that in the instructions. People are siliconing every thing. No need for that. It is a dry well so water isn't getting inside of it. It comes with a gasket. Just have to make sure you put it on the water side. Put it in there. Tighten it up. Then put your sensor in. Simple as that. I don't think I'll ever do any controller that doesn't have a sensor in the tub vessel. to much variance between the readout & the actual water temperature

First, was unable to insert sensor into well. Was able to drill out without ruining sides, so turned out fine.
