Need a gasket that goes between regulator and pressure gage assembly an the pressure switch.

Do I need to change the entire assembly?

Joe, I've uploaded an image of the area on the 95386 that shows the regulator and the pressure switch.

I don't have one in front of me, however, your question suggests that the nipple from the regulator doesn't thread into the base of the pressure switch, but that there is some sort of gasket?

Never heard of that, me.

This were my compressor I'd remove the regulator assembly, add a nipple between it and the base of the pressure switch, thread the regulator onto the nipple.

Then I would and add a checked coupler, the same make as your connectors, where what I perceive to be the small ball valve is on the right of the regulator.

Or, am I missing the boat entirely about your question?

pressure switch diaphragm replacement

Just opened mine up, and its busted as well...in almost the same way as yours. has anyone tried cutting an old truck tire inner tube to the same shape. I imagine it would probably do the job. I'm gonna try it tomorrow.

I've never had much luck chasing down parts for these low end air regulators, Bob.

Since I just checked and you can buy the whole regulator on line new for $17.50 plus shipping, it's hard to think that you can find the part, then spend the time necessary to tear down and rebuild the old one, for less than the cost of new.

If someone does have a source for regulator parts though, we'd like to share that news.
