redesigned part
You may have some difficulty getting this to fit in your water heater shell, as it has been redesigned. A bit larger than the previous version. It all depends on which water heater tank you have. Do it yourself. Don't pay a tech 100's of dollars. It is very simple to install. Works like it is supposed to.

Not a direct replacement aquastat for Triangle Tube SMART 30
I was disappointed that this part was not a direct replacement for SMART 30 installed in 2012. The original aquastat was IMIT TR2 9338, but this particular model is discontinued by IMIT and Triangle Tube apparently substituted with this part. It does not fit into the compartment nicely since the physical dimension is slightly larger (taller) and the mounting bracket orientation is 90° off.
No issue with the fitment of the sensing bulb and the capillary line into the drywell.
It does function and I could not find IMIT part so I will keep it and drill 2 holes on the plastic cover plate to accommodate the mounting bracket orientation.
I am not impressed with Triangle Tube... As far as SupplyHouse goes, they are top notch.

Right on time!!
Really needed the aquastat fast. I had no hot water. SupplyHouse came through when other suppliers didn't and I had to cancel with them because their delivery date changed too taking longer when I ordered.

Price and quick shipping!
Ordered an aquastat for my Triangle Tube indirect water heater. This was an exact replacement I needed! Easy to install and saved me about 700 hundred (plumber costs)
