Rebuild or repair your Porter Cable air compressor with this Z-D28777 pressure switch.

It includes the unloader valve and lever—everything you need to get your compressor cycling correctly again.
It's a brand new replacement part, made to fit Porter Cable models.

The switch controls when the motor kicks on and off based on tank pressure, and the unloader valve releases head pressure for easy starts.

If your compressor isn't building pressure or won't shut off, this might be the fix.

MPN Z-D28777 is the one.

No UPC listed, but it's the real deal.

Easy to install for anyone handy with tools.
Get your compressor back in action and get back to work.
