Diaphragm on pressure switch is leaking.

I have an old red line 14 gallon compressor and the diaphragm is leaking air. I took it off and it looks like dry rot. My question is where could I get the rubber diaphragm, or will a new switch fit my old compressor?

Ed, I can't tell you if a new switch will fit your old compressor as I can't see what yours looks like.

However, think about what the pressure switch does on your compressor, and ask yourself, can I mechanically or plumbing wise add a different make pressure switch?

A pressure switch just turns power on and off based on the pressure the switch is sensing. Except for toggling the unloader valve, if yours does, those functions can be replicated my many off-the-shelf switches, if you can plumb and wire them.
