Breech plug thread Grease.

[Gooddaytoya!]

I've read many times that you have to use special grease on the threads of a breech plug. What is special about breech plug grpease? Would wheel bearing Grease work just as well?

I think your asking about an "anti-seize" lubricant.
Anti seize is used in high pressure/torque applications to prevent threads from galling of the two pieces. The stuff stays in place and won't weep under pressure or high temps.
Tiny amounts of anti-seize is all that's required. I've had the same tube of Permatex anti seize around the shop for the last 20yrs and it's still over half full.

Axel or bearing grease is intended as a moving parts lubricant, it's designed to move freely (much higher viscosity). If used for a breech plug it would pressed out of the highly torqued threads (weep)

Makes sense. I've heard about that purpose for bearing Grease. I'll take your advice and go with the permatex. Thank you.

I’ve used no grease or anti seize on many breech thread both muzzleloader and breech loaders. In gunsmithing school we were taught to do this kind work and grease of any kind was never suggested. Building custom rifles full time, I nor anyone I worked with used nothing on threads. While working at Shiloh Sharps the barrels were fitted to actions with only the oil from the bluing process. Do what you see fit.

I now use only anti-seize, but many years ago I used common grease and have no problems with the guns made then. The breach seals are still good after forty years. I would have to remove the breech plugs to make sure the threads are still good but I have not had any reason to remove them.I do know from experience on farm equipment that common grease will prevent rust for over forty years on bolts left out side.

The advice the OP is talking about would refer to the modern front-stuffers we don't talk about here. There is breech plug grease sold for that purpose.

I use Breech plug grease for the nipples in my Renegades and Hawken

I use CVA slick breech plug/nipple grease. The stuff works well and I've never had a problem removing any parts I used it on. I use it on everything from nipples, breech plugs, and vent liners to the threads on ramrod jags, pullers, and fouling scrapers.

A little about high temp anti seize lube, I use it on my tractors lift turnbuckles. After a year of bush hogging and tilling with all the dust and debris and often sitting out in the rain they are rust free and still turn just like the day I lubed them.

I use it on my breechplugs, I put a lot on, even if I missed a tiny spot with my plug breaching, no water is ever going to get past all that anti seize.

Well I had a machinist remove the stuck breach plug, and I bought a tube of permatex anti-seize compound. It works great: I can tighten the breech plug really tight to get it in it's proper position, yet can still remove it. I had gotten myself into a jam there. Thank you for your advice.
