I had a scare when I decided the nipples need removing for cleaning.
That can be problematic.
Repeated removal and reinstallation will eventually lead to your risk of pull threads out the nipple or hogging out the cylinder thread demensions.
Is that faulty reasoning?
The only reason I broke 3 nipple wrenches was to remove nipples for cleaning cylinder threads that wernt rusted as feared.
While it has been debated before, I'm a firm believer that it is faulty reasoning.
Perhaps you have a factory thread problem or the quality of the older ASM metallurgy led you to feel that way.
But I use breech plug grease and barely snug the nipples down after each shooting session and cleaning and the threads and nipples do not suffer any wear & tear ASFAIK.
And I have never seen one nipple back out at all either, even though I use the lightest amount of torque possible which is practically nill.
I think that removing nipples for cleaning & lubing each time is preventative, especially if they're babied when installed.
The grease may help to keep fouling out of the threads, whereas torquing them down hard probably won't help solve anything but can create problems with their removal, especially if not done regularly or without using anti-seize.
When buying a new or used gun, if removing the nipples was a problem, then I've put the cylinder in heated to boiling water for a very short time which has worked well so far.
I like the RMC nipple wrenches and haven't ever ruined one of them.
