Looking for vintage packing nut

[Ratherman]

I am looking for either a packing nut or the whole valve. Here are some dimensions:

3/8" shaft
3/4" threads
nut is 5/8" long, hex is 7/8"

Appreciate any help,

You'd have to find an old school plumber or farmer who has a bunch of junk in a pile; or wanted to braze it back together.
FYI, Water piping that old (speaking of galvanized steel) is way past its prime and a liability so, should be replaced anyway.
You may strong-arm a plumber to use other methods like compression repair couplings.

Shut this valve, install a new one above it

Then open the bottom valve FULLY which we normally don't do and this should stop the drip by the packing gland nut

If worse comes to worse get Propoxy by Hercules and follow directions

If your only symptom is dripping from the stem, I would just add some packing cord under the nut, around the stem clockwise, and then tighten the same packing nut down. I like the white PTFE stuff, and others prefer the black graphite type.

Some valves actually isolate the packing nut area if all of the way open, but I don't think yours is one of those. So you will turn off the water and relieve pressure before enhancing the packing.

Also, get an open end wrench that fits, or get a good big adjustable wrench.

There is a copper union under that valve.. Much easier to replace it with another threaded valve than it will be to find a replacement packing nut.
