It’s a porter cable pancake compressor. 135 psi 2.6scfm @90psi 2hp 6 gal.

It keeps blowing rubber air line from compressor to tank.

It heats up and blows the line cause it gets too hot. Why?


Blowing Air line from pump to tank
by: Bill

If you were making an air compressor to sell for $100 or $150 you’d need to use cheap parts.

The line from the pump to the tank is one such. Rated for elevated temperatures, it obviously does not have the heat resistance to withstand your compressed air temperatures.

I always recommend that, if you are having problems with this air line, swap it out for soft copper tubing available, with fittings, from a good plumbing shop.

As to why the air leaving your pump to the tank is so hot, could be a number of reasons. If you are using the air compressor for extended periods of time, exceeding the duty cycle of that air compressor, then it will get too hot.

If your power supply is hampered by an extension cord, the motor will overheat, heat up the pump, and add heat to the air.

Using your Porter Cable outside in the hot sun will add to the heat load.

Running the compressor while it is overheated will damage components and lead to sooner rather than later maintenance work.

Hello! My hose on my compressor busted, and I order a new hose online (forgot which site I got it from; probably e-replacement.com); anyway…
Clamp didn’t come with so purchased 3/8 pex clamp from Lowes, but once I put the head back together, the hose heated up.
I noticed that lately, the compressor has been cycling for extend period of time. I mean, it seem to run a little longer than it use to. Kind of apprehensive about that. Should I change the cut-out switch (if that’s even possible) or just get a new compress (which I already have)

I’m having trouble visualizing your situation. Could you take some pix of the the hose and clamp area you’re talking about? Also, please give the make/model of your compressor or at least a pic of it. Maybe a pic of the old hose, too, if you still have it. On the pressure switch, it’s usually not a good idea to change it. If it works at all, chances are it is working properly, and the source of the cycling and longer run time is a leak somewhere. Having said that, there’s a chance the pressure switch itself is leaking. Can… Read more »

Thanks for the reply. To be clear, when the tank is empty, it seems to run over the 150psi cutout, but everything else seems to work. Yes, I can hear the pressure release once it’s full or the tank is satisfied. It’s just that, after I installed the new hose, it (the hose) became hot. Now I’m not sure if it’s supposed to get that hot, but… I’ve been reading that heating up of the hose is normal, but I’m thinking that because I’ve had this compressor for so long, it’s just age. And that could be the culprit as… Read more »
