PORTER-CABLEPorter Cable N003307SV Pressure Switch (1 Hose Clamp Included)

Used for air compressor

My compressor did not shut off... had to manually turn off and on which was a pain. I figured it was the pressure switch so I got it. I am glad I did. The directions were okay... they did not say how to get the motor off the tank (look closely on both front and the back and you will see 2 black screws on the lower side by the tank mounts... remove those and slide the motor off).The switch did not come with a mounting screw or clamp like in the picture. I reused my screw and just happened to have a worm clamp. Put the switch on and fired her up and works great!

This part was identical to the original and did not require any additional modification. The pressure settings are accurate. The part replacement was not difficult.

I have a small Porter Cable air compressor and it suddenly failed to regulate tank pressure. Googled the problem and learned it was likely a bad pressure switch. I matched the part to this one and purchased it. I reviewed an online installation video and the included instructions. This was an easy repair and the part works great! You will need a few tools to replace this part- screwdriver, torx bits and long shaft extension, pliers, heavy-duty cutter and an ear clamp crimper. I used a hose clamp instead of the included ear clamp since I did not have the proper crimper. I’m happy with this purchase. It arrived quickly and complete with all parts required.

Not the easiest install but not the worst. For my generation compressor the tube was about 2 inches too long but it was an easy trim. Back to cycling between 120 and 150psi as normal.
