I used anti-seize compound back in my drag racing days on spark plugs, cylinder head studs/bolts, exhaust manifold bolts, etc. Now I use it when tightening down the compression fittings and boiler bolts.
Take my word for it, a few bucks now will save you a lot of heart ache later.

You read my mind Robert. :icon_puke_l: I think I may have some in the garage that I used on my spark plugs, but I'm starting a collection of stuff and goops for when I open my steam boiler in a few months.
I'm also thinking of insulating the steam boiler afterward.
It's especially important to use it on the connections to the group. Galling is a MAJOR problems there.
