Was lucky to find this part.
I could never fathom paying so much for a part, but when you need it, you need it and I'm glad it was available.

Parts missing-had been installed
The part came in an opened box, a screw was missing from the bonnet, a fitting was missing from the backflow preventer, and someone had installed a pipe fitting in the regulator. (Had the furnace not been down-I would have asked for a replacement.) I hope it lasts!

Perfect fit
This product was a perfect fit for my hot water boiler system. Installed in about 10 minutes along with a new expansion tank.
