Mech Power M90002- my base of pressure switch (cast metal) broke off.
All components of the switch were in working order, I just need the base metal part. the gauges and switch are all good . is a base part available? if not, is the entire assembly available?

I doubt if you’ll find an OEM pressure switch, though I expect you will find after market switches that will fit.
I’m curious as to how the base broke? I had one go on another compressor, the result of an over-tightened fitting or a flaw in the white metal.
See https://about-air-compressors.com/buying-a-compressor-pressure-switch.html for some guidance in finding a new switch if you need it.

Pressure switch
Looking at other pix of this machine, it looks like the switch itself is not broken, but a pipe broke off in it.
That broken piece can be removed, but then where did it break *from*? I think the tank – is that piece removable? Then all you’d need is a short-ish piece of 1/4 inch pipe, from the look of it.
Maybe send a pic of what it broke from, if I’m way off-base?
I need the copper line from the tank to the pressure switch. I am retired HVAV pipefitter and I’m unfamiliar with the tubing and size fittings to make the new part. It appears to be metric equivalent of 1/4 ” flare fitting on one end and compression on the other end. The tubing was not soft drawn copper.
