⚙️ N003307SV Air Compressor Pressure Switch Kit for Various DeWALT Models Review

My compressor wasn't shutting down properly and the relief valve opened. I thought I needed a new block until I found this switch. Easy to install and now my compressor works as it should.

Although the hose is the right size, the pressure switch is undoubtedly the right psi. The assembly protrudes about a half inch beyond the compressor housing and will prevent the motor assembly from seating properly for housing reinstallation. If you don't mind hanging the switch outside of the casing, you can do without this device.

I had to remove the rubber grommet to install it on the compressor and the only way to do this was to cut it off. It's not obvious until you try to assemble the case, and it's painfully close but not fully closed. The required pipe clamp was also missing. I've charge cycled it and it seems to work, but the supercharger charges to 155psi instead of 150. Not very impressed. If the part fails within a year I will update the review. The bad thing is I needed it fast so I skipped the cheaper option.
