You may have answered my question with your response to this question. But I might have a different issue, maybe not..

The regulator seems to be continually slowly bleeding off?

_______________

I just finished installing my new used Ingersoll Rand compressor. It is a 2 stage 175psi compressor. I installed a regulator which is also used that came with the compressor, Coilhose pneumatics brand. My problem is that it leaks or is bleeding off overage pressure coming into the regulator near the T handle. There is a hole which the air comes out of. I have the outgoing pressure set to 110psi but the incoming pressure that is higher than the 110 bleeds off through the hole near the T handle. I close off the incoming air and the pressure in the line stays at 110psi.

Why would the regulator leak any pressure higher than what it is set for?

You are very welcome, Tom

I'm glad my air compressor and related products information was of help.

I take it that you didn't acquire this regulator as new?

Regardless, glad you were able to find out what was wrong, and good luck with the regulator rebuild kit.

Hi Bill,
It is for for compressed air, up to 175psi. I have verified that I installed it correctly and I did not sweat the copper while it was attached.

I called the manufacture and they sent me a quick email directions on how to take it apart. He said in most cases there is debris preventing the seal to happen. I took it apart and it is filthy inside and the diaphragm spring has been corroded through and broken. Looks like I need a rebuild kit.

Thanks Bill. I appreciate your web site and help

Tom, nice installation and thanks for including the pix.

What fluid are you regulating, please?

Are you sure the regulator is installed in the correct orientation of flow?

Is there a reason why the downstream air pressure may be higher than the set point of the regulator?

Did you sweat the copper fittings when the regulator was installed? May have damaged the diaphragm through heat transfer if so.

Bill
