Sealing a house radiator at the nut

Despite a fairly tight turn with the wrench, when the heater system runs, there is a slow drip from the nut. I would like to simply seal it with something anaerobic or some sort of epoxy, and one that can withstand hot steam. That's hot.

There are probably dozens of products, I just need one. I don't know if Permatex has something that can withstand the temperature.

I don't want liquid teflon products - I don't think they are the right product.

I've heard of Permatex's, Loctite's, Sydglass, LacoLoc, Vibratite, Basswhite, ..., perhaps one of these companies has something. I would favor a high temperature sealant that hardens like a resin. Do the automotive stores have something?

Naturally, I would prefer something that has low back-wash into the plumbing but I'm not that worried, as long as it dries, it should be ok.

It's ok to recommend more than one product - I assume this is a fairly common problem.

I could turn the nut more and more but I am just being careful. Perhaps that's all it needs, perhaps not.

I want a solution that's not so time-consuming waiting to see if it leaks.

There is no miracle sealant like in "as seen on TV".

You can't seal the nut...... just the ground mating surface.
A little bit of plumbers pipe dope on the mating surface.

I don't know of any products called "plumber's pipe dope". Do hardware stores sell this?

Pipe dope is used by plumbers therefore it is plumber's pipe dope. It's as common as dirt. https://en.wikipedia.org/wiki/Pipe_dope

Everybody, including plumbers, call it "pipe dope," but it's not called that on the bottle. Any hardware store worth its salt should know what you mean by "pipe dope."
