Coleman VP0502010.02 blows regulator cap off

by Chad
(Western KY)

I have a Coleman Powermate VP0502010.02 compressor. When I set the regulator to more than 75-80 psi it will blow the regulator cap off, scattering the gasket, spring, etc.


I have made sure the regulator cap is screwed on tightly and isn't cross threaded.

What is causing this to happen, and how can I fix it?

Good compressor that works fine, other than this problem. I'd like to be able to run about 90 psi for pneumatic tools. Thanks for any and all help.

There is a repair kit, about $50:

You can even get the manifold! Often not the case.

As you increase pressure on the regulator setting, you are depressing a spring. This increases force upwards, away from the spring, as well as increasing the force needed by the air to bypass the regulator, resulting in higher downstream pressure.

Though you may think that you are securing things tightly, something inside the regulator has failed, and as you increase pressure, that pressure overcomes the force holding the regulator together, and apart it comes.

If you cannot find any OEM parts for this compressor, and since the regulator is part of a manifold, you've got a problem.
