metallic tape for exhaust ducting

Hello,

At my parent's home, they have the furnace man come to service their unit each or every other year. It is a oil/coal stoker.

I noticed that the man puts some high temperature metallic tape around the connections from pipe to pipe from the furnace to the chimney. Since there is a right angle, a riser, another right angle and then the short straight pipe into the chimney, there are a few to do...

Im curious what kind of tape I need to look to get in order to do this on my exhaust ducting from my furnace to chimney. Ive not seen any high tmeperature metal tape at Home Depot, though I might not be looking for the right stuff.

Any thoughts???

Thanks,

JMH

Tape

The vent pipe joints should be sealed with high temp silicone. If the tape has to be replaced each time the unit is serviced, I would guess it is not holding. Most likely the glue is is burning off. The only high temp tapes I'm aware of are those sold in automotive stores as a bandage for mufflers.
