Restoring an air compressor, starting to get parts in from China. Decided this needs replacing too (corrosion and some play) but can't seem to google it. The male side is 1/4" haven't measured the female side.

Take a run over to Princess Auto, they're got a pile of NPT adapters.

What/where does it connect on the compressor?
Looks like a pipe with a flange connector on one side and MPT on the other.
Are the threads tapered?
Is that an o-ring inside?
Does the "nut" turn freely?
Do you have a set of thread gauges?

Pressure switch to tank.

Yes definetly NPT on the male side.

That's a circle of rust inside.

One direction. Jams up a bit in the other.

No

Are you replacing the pressure switch? Most replacements will just have female pipe thread inlet, so you just use a short section of pipe with 1/4" pipe thread on each end.
That part looks like a custom fitting for the pressure switch.

Yes. Guy I bought it from had it torn apart.
New pressure switch has the same inlet as the old one.
So the 1/4 goes into it, and the female side bolts onto the tank.

So it is actually 1/4 NPTM and 3/8NPTF
Princess auto only had a solid connector, which works, but it's a pain in the ass when you forget to wrap it with teflon and then have to pull the whole thing back apart. Ask me how I know :D

On that note, works great. Canadian tire has a impact wrench / chisel / tire inflator / everything else kit on for $100 :D

Sweet! Glad my tip paid off.
I've got a small 2 gallon compressor, but it's useless for much besides inflating things and blowing dust.
