just Wondering What Would Work Best To Seal The Pipe Thread Fittings On My Exhaust Manifolds. The manifolds Have A Threaded Fitting and i Need To Put a Pipe Plug Into It. wanna Make Sure It Seals.. Thanks
 
Rector Seal is what I use. you can buy this at the plumbing shop. Or Real non hardening quality pipe dope, there are different brands.

Agreed. We call the stuff "rectum seal" in my business. :)
Give the plug a few "rounds" with Teflon tape, then apply the Rector Seal on top of that. Install the plug while the stuff is still wet, then wipe off excess once in place. Done deal, won't leak ever - and bonus, you'll be able to remove the plug in the future if need be.
 
I would use anti seize compound if you ever want to remove the plug.

White Teflon paste. Never leaks. Easy to remove the bolts.

Because of the heat involved in those kind of situations, I use anti-seize that I buy from Ford that they sell for their 5.4 spark plug lube. Good stuff ! Again, if you would ever need to remove. Wouldn't be too concerned about exhaust pressure leak past a tight pipe plug.
 
Would Red High Temp Rtv work?
Not a good choice - it's silicone. RTV red is a gasket maker, sets up and becomes hard. While it probably would seal, it would be a mess. Products like Permatex High Temp Thread Sealant, Rector Seal, etc not only seal, they lubricate so you can removed the bolt/nut later. Using a product like RTV would create a mess.

Any suggestions for this?
I do not want the pipe to seize or threads to deteriorate. It seems anti-seize would simply burn away.
I replaced the manifold on this old girl last year because the threads on the pipe and manifold were gone.
Other than that it was still ship shape. I suppose it did take 60 years for the threads to corrode away.

Don't know why but rectum seal came to mind when I read the OP's post. Probably heard the term before somewhere....Old Timers is really kicking in these days.
 
Why are there so many exposed threads? If they are not being used, then can you paint them with hi-temp paint.
 
The blue Rectum (errr, Rector) Seal will act as an anti-seize to an extent; it doesn't go all epoxy hard on you.
Trust me on this; what I do for a living is always piping, most times threaded into cast fittings. Sort of what
fire sprinkler systems are made of, short of the grooved end big stuff.
Between the Teflon tape and the sealant, nothing leaks and you can take it apart later.

Man I hated getting that stuff off my hands. We went to blue monster and it’s much easier to clean up!

Did you ever use Keytite? It was green and as far as I could tell totally insoluble, I 'd get it on my clothes and had to wear them out before I didn't have to look at it. Ah the good old days!

There's trade-offs to any product. The key is not to get it on your hands to begin with. :)
If you let it harden on your fingers, best get out either a ScotchBrite to scrub with or a pocketknife to scrape with.
