Permatex

I noticed last night a little smell, and I am out of Rutland High Heat silicone, so I ran to the automotive store and got some permatex orange high heat. I am just riding it out till I can pull this pipe. My stove adapter now looks like vinnys, until he redid his with Icc Excell pipe. Is that stuff pretty tough, I have a month and a half to go before I shut the stove down. I have used this stuff on valve cover gaskets, but never a pellet stove.

What's their definition of "high heat"?

I have the ultra black on my pellet pipe joints inside and out. No issues. Rated for 800 IIRC. Tubes should have the heat rating on them.

If it's the Permatex Ultra Copper then that's what I used on my pipe and door gasket. Works well and rated to 700F.

As long as its 500 rated I think your OK. Check the rutland info above.

Jay the rutland is what I always use, the link to the pematex, is what i used this time, since i was out of the rutland product.

650 should be just fine.
