Anybody ever use this kind of product?
Exhaust Wrap
I'm thinking about using it to wrap around the joint of the t-connector and flue collar.

There was a recent inquiry looking for a product to repair tape a broken fitting and I thought about this product. There is also muffler bandage. I have not tried it in a stove application and can't comment on it's appropriateness for this off-label usage. First concern would be the inflammability at high temps. The second would be fumes coming off of it.
Those were my concerns as well, but I would imagine with it being rated for 2000 degree temps it would never combust.
Side note: I just spoke to a Thermo tec rep and he said that the material is not flammable and is made from a fiberglass material. He did say that the product will cure for about 30 minutes. During this time it will smoke, but the fumes are not toxic. Probably similar to curing a new paint job on the stove.
Here is a link to the MSDS.

I think I'll give it a try. I can't get the t-connector to seat good to the flue collar. I had to cut out some of the t-connector so it could go around the damper. Basically there are holes on the connector they do not go all the way inside the flue collar so room air is able to enter the flue at this point. This could cool the exhaust quicker plus in the event of a chimney fire it would provide a continous source of O2 to the fire.

I purchased the wrap from NAPA today. $23 for a 15' roll of 2"x15' graphite black. The weave is very tight and the material is very sturdy/strong. It should work perfectly for my application. In fact I plan on using it as the gasket wrap for my combustor as well. I doubt it will expand like the traditional combustor gasket, but the thickness of the wrap makes a very snug fit in the combustor chamber. I believe the specs say it is 1/16" thick. I think it will last much longer than the gaskets that come with the combustors.
It would be interesting to find out if the insulative properties would be comparable to the traditional blanket insulation for liners. If so, creating a sleeve to cover a 6" round liner could make a big difference in effort compared to using the blanket wrap. Plus it wouldn't add the extra thinkness to the liner so slipping it down the flue would be less of a challenge.
I can't imagine it would hold as much heat in as the blanket, but you never know. I'll try and do some experiments. Even if it was 50% as effective as the blanket some folks may be willing to sacrifice the additional insulative value over ease of use. Of course price would play a critical role. I wonder how much it would cost to make a 6" diameter sleeve 20' long out of this stuff?
I've searched a lot of car and motorcycle forums to see if anyone has pre-wrapped and post-wrapped temperature measurements, but didn't find anything like that. The closest I've come is the guys mentioning that with the headers wrapped, they can grab the headers with bare hands after being driven for a awhile.
