Porter Cable WILL NOT BUILD UP ANY PRESSURE

Bill,
I have a Porter Cable 25 Gal upright 135 PSI Model # CPF 6025UP.
Motor runs great, pulling air thru inlet but no pressure at all. Checked all plumbing no leaks. I really can’t figure this one out. Ant ideas ?

Hello Joe.
You’ve ruled out the valve issue by checking that the intake port is actually drawing in air and not blowing it back out. That suggests that valve is fine.
Do the same for the line that goes to the tank from the pump head, and be sure that air is being pumped out strongly. Try to stop it with a gloved finger. You shouldn’t be able to.
If there are no leaks, all other things being good on your air compressor as they seem to be, my guess would be a gasket failure under pressure inside the pump.
Cheers,
Bill

the tank air pressure will not build past 60 psi, and the regulated pressure will not go past 60 as well. bought the tank new ran for 2 years.. 5 days a week. i am thinking piston ring,
Add a question about your Porter Cable compressor and its problem with building pressure?
Use the form below. Add a photo or two too, K?

I have the 6 gallon pancake. I would not build pressure over 110 pounds. I replaced the piston ring. cylinder, valve plate, gaskets, outlet tube seal, and regulator(my old one didn’t adjust too well). Now it will go to 120 if I let it run long enough. lol Never shuts off. I thought for sure all this would make it like new again but no!
Bill my 6gal 2.6 SCFM Will not build pressure past 50psi, any ideas
Pancake compressor, replaced tube seal, head gaskets. Still won’t pressurize, plus hose going into tank seems to be really warm, quite a bit more than I remember, Any thoughts/ideas?
