I wanted to fill everyone in that uses these t-stat housing part numbers. Here is what I learned as the 12678779 is now a non-active part number.

In place of 12678779, use the housing 12678780, and seal 12623519.

My shop foreman states the pipe 12669654 is rarely needed and not necessary, but available.

They alternated which one is on back order, for the last year or so. Only a $108 apart on the retail side. Customers love it!

Is 12678780 the final in the supersession chain? I show 12678780>12732857>12734896 in PWB+

The plot thickens.........

No pricing on any of those Denise and I was able to scoop up some 12678780 for stock. Just need some seals now.
