3M High Temperature Flue Tape, High Heat Sealing Tape up to 600 degrees, 1.5' in x 15" ft Roll, Stops leaks from hot air ducts, Made in the USA, Silver (2113NA)

Had a leaking flue pipe joint when heavy rain. Adheres well.

Easy to apply, strong and did the job sealing joint on flue.

Used this tape to seal a metal flue from a gas fired heater. Don't use this to provide a mechanical seal, use screws and place the tape over the join to make airtight. Remove all loose rust etc and clean first, then the tape sticks very well. Good easy to use product.

What I was hoping for a thin durable hi temperature tape.

Good quality tape and a brand name and very strong glue

Bought to cover hole in steel stove pipe but the tape doesn't stay stuck and just falls apart. I realise this isn't the proper use for this tape - it's for hot air pipe rather than a burner chimney. But I thought it might work since the stack pipe certainly doesn't get hotter than 600 degrees F. So this is not so much a criticism of the tape (although it seems very expensive even if it does work on hot air flues) as a warning to anyone looking for a way to mend their stove pipe - this won't work!

Perfect !

Don’t bother
