Product worked great
I had to replace the bracket that came with this product with the one on the original pressure switch so it would mount correctly, but other than that the pressure switch works great as a replacement of the one that broke on my furnace. I'm glad it came with the 1/8" hose barb to 1/8" npt connector because I couldn't find one at any store.
