Need help finding nut

Member Posts: 44
I have a radiator with a valve that has an unusually-sized nut on the part of the fitting that seals off the valve stem. The shaft is the same size as my other valves, but the thread is much larger. I’ve put a standard one in the pictures to show the comparison. I’ve been to a few plumbing supply companies and no one was able to find me a replacement. There’s no union anywhere nearby, so I really don’t want to have to cut and rethread to replace the valve.
I need a new nut because I over-tightened the existing one.

Is the nut cracked? I just see a small hole. Maybe it the hole can get a little weld/braze, and the valve repacked?

Every valve has a different packing nut size. Your best bet may be to find some old valves and see if the nut from one of them will fit. Or, get the original nut brazed or something similar.All Steamed Up, Inc.

Or take valve to a machine shop and have a machinist mill one to match.gwgillplumbingandheating.com

If you show it to a web site that specializes in selling older faucet parts they might have a packing nut that fits.
If it isn't actually split, you might be able to put a brass washer inside it.0 -

You might be able to use a 2-part epoxy like metal-set/JB Weld/etc to patch it. Otherwise I'd look for a local machinist or a high school with a machining course that might like to give the students the challenge of measuring and creating the piece.

I think you'd be better off just replacing that valve seeing as the stem appears to be broken. As It's not a union valve that should be relatively simple to do. Save yourself the trouble of fighting with that packing nut.Miss Hall's School service mechanic, greenhouse manager,teacher and dog walker0

Couple pictures from a few feet back would help0

Just a thought...It looks like the top of the nut split and blew out. I'm wondering if a heavy brass washer were fitted to the nut (after the broken bits were removed) and then soldered, or silver soldered into place, might that be sturdy enough for the job?
