High temp silicone

I just looked at the tube again. It says High Temp Silicone. Withstands temps up to 2000*. Interestingly though, Rutland's website only shows a 500* and 600* for their high temp silicone.

 

That should work just fine Geek.

Just so the folks know, if you can't find High-Temp RTV at the local hardware / Box store,

an Auto Parts store is your friend -

Permatex High-Temp RTV is rated to 600 degrees,

Permatex Ultra Copper is rated to 700 degrees,

and both are essentially the same as the Rutland 600 Red RTV gasket product ..

 

+1 JT - Sub, you would have to chisel that stuff off (if it is the cement), had to use that on a firebox repair years ago - strong stuff - .

 

Well if that's the case the guy at the hardware store don't know chit. I bought it and was sitting in my truck and questioned whether or not I had the right stuff and went back in the store. He showed me a kit they sell of rope gasket and silicone and said what I bought was the same stuff as what was in the kit.

Fortunately I only had to repair a 2 inch section of the door gasket that had come loose, but it sounds like that is going to be a PITA to get out next year.

 

It will come off, but you may be using some muscle and a hefty screwdriver / or a dulled chisel to scrape - using a Dremel tool w/ some precision will speed things up considerably, speaking from experience.

 

I went to Rutlands site again. It is the cement.

 

No worries Sub, just will take a little longer to clean up on next gasket change - at least you know that section is staying on there this season!

 

My plan is to twist lock the pipes really well and place a bid of silicone on the junction outside, not planning to put silicone inside.

 

If that makes you feel comfortable w/ the install Geek, then go for it - that's what you should do.

 

There are several 2000 degree items that are actually cements, they are not sealants, I have used various 2000 degree cements for things like returning an old gravity hot air coal furnace to operation and they can actually bond metal to metal in some instances. The gasket cement I use is a 2000 degree product from Rutland. I would never expect to get anything apart that was joined with that stuff without likely damaging at least a bit of whatever was joined together. I have an unopened tube of some "furnace" or "retort" cement also a 2000 degree item.

 

Any auto parts store will have it. Even Wally World carries it...

 

Question for you guys, after all this talk about the 2000 degree cement Sub got for his door gasket. I have done gasket jobs on my wood stoves in the past and it was always done with the super cement sub got. Now, I have never done a gasket job on a pellet stove, because neither of my stoves have needed it done yet (knock on wood). However, if/when they do, I would have just naturally gone ahead and used the exact same super cement. Getting the impression from this thread, that is not correct. So...what is it that's used to hold the gasket in place on a pellet stove? The same Rutland 500 / 600 degree silicone you use to seal flue joints?

 

AFAIK, all the stove manufacturers use the high temp silicone. When I replaced the gaskets on both of my stoves, they had silicone holding them right from the factory.

 

I don't believe that's silicone....so wont stay flexible. The problem with stuff that gets hard is that with the expansion and contraction of the vent pipe, it may crack and leak, which tends to be bad.

If it isn't seen, I like Super red, if on black pipe, then black RTV, galvie pipe would be clear. Rutland makes all 3, in small squeeze tubes and larger caulking gun tubes.

 

I have tried our local Ace store and they have the full sized calk tubes of high temp black.

Waaaaaaaaaaay tooooooooooooooooooo large a quantity.

I headed over to the Napa next door and get the small tubes in Black, Red, Copper color

 

Welcome Snowy Rivers!

Nice to see you here!

 

The other joint was getting a tad stale.

I still frequent the place but I enjoy a variation of chat.
