Description lacked critical info.

The order shipped and was delivered promptly. The part fit properly and looked just like the one in the picture. So far, so good. The problem is that my original had on/off psi of about 115-125. This one is 145-175, my tank is rated at 150psi, so this was a problem. I ended up dialing the adjustment screw down to the point where I'm not sure if it's still within the recommended range on the switch. Time will tell. The pressure range of the switch IS NOT LISTED IN THE DESCRIPTION. This is an important piece of information, so it cost you a star.

Intermediate install

Should come with thread sealant since it's necessary for the install. The switch assembly has to be removed/installed in order because otherwise you can't spin the attached parts to remove them. It's fairly easy to figure out that order as you go (remove each obstruction...then replace in reverse order), but it would be nice to have instructions. Wiring is tricky to see if you can't move the compressor into open space. Take a picture of the wiring before you disconnect and use a mirror to help reinstall.

after installing the part and starting the compressor, the new part leaked air from the same valve as the switch I was replacing.
