Inside An Air Regulator~ Because you don't trust the one on the compressor

Ah those magical devices!  They regulate your air feeding into some contraption.  Ever wonder how one works? You didn't want to take apart your $50 tool though, so you lived in ignorance.  Until now.

I have an air regulator.  I bought it for a quarter at a yard sale.  It worked great, but then started leaking along the gasket in the middle.  I figured I could fix it easy.

My Regulator hooked up.

Gasket thing.  It wasn't sealing against the metal well.
I puts some hylomar on it and that did the trick.

Button that is pressed on by the dimple in the piece above.

Input.  Unfortunately, you can't see the gizmos in there.  Not anything significant though

You are enlightened.  Remember, you heard it on Maniac Mecahnics first.
