I am looking for a fitting that will allow be to have a pressure gauge
near the inlet of my city water so I can always see what my pressure
is. I live on a hill near the water tank and our home pressure runs
about 40 psi most times. I would need a tee fitting that I could cut
into the 3/4" copper piping to allow the water through with a port for
the pressure gauge I have [Merrill PG100 with a 1/4" male thread]
Does such a beast exist or am I going to have to build something up
with brass fittings?

Hard to tell what is available in your area, but you should be able to find
a 3/4" sweat tee, with a female thread that you can bush down to the gauge.
If nothing else a 3/4" tee, with a female NPT adapter soldered to it.
Many other ways of building them...
Ones one the system here last for several years at least and then it's
rarely the gauge itself that fails, it's accumulated rust/sediment.
Units work in power plants for years as well...but, of course, they're
All of the above are typical except perhaps reading high.
The least bit of corrosion from a wet or condensing environment will spoil
the little gears and bearings.
If you ever have a bad one to throw out, tear it apart and have a look.
Looks like the proverbial ladies watch.
Here's a pretty good explanation and diagram:
