Ratings & Reviews+

3M Canada High-Temperature Flue Tape is rated 3.4 out of 5 by 7.
Rated 4 out of 5 by from oven patch I used this product to cover cracks on a Nuwave oven. It seemed to do the trick as I used the oven yesterday and it held up to the heat.

Rated 5 out of 5 by from Works great for oil burning furnice. This tape is great for sealing connections and seams on my oil burning furnice flue pipes. It has been two weeks and it is holding great. I was able to even apply it right where the pipe connects to the furnice. I was surprised that it is holding there as my furnice is 20 years old and this spot is very hot, unlike probably the more newer/efficient once. Just a note - if you need to have 2 layers on top of each other, dont touch the bottom one too much with bear hands as the oil from your fingers will prevent the top layer to stick and it will peal off shortly after. Downside - tape is very short, needed 3 rols for 10 feet flue pipe - connectios and seams.

Rated 3 out of 5 by from High temp Flue Tape I guess when you need it, it works enough. I found the tape not very sticky. I find it hard to seal any air leak when it isn't really tacky enough.
