First, what you do not want to use is duct tape, the adhesive fails under the extreme temperatures.

For dryer vents and HVAC ducts, you should seal seams with a foil backed tape. This is designed to be airtight and handle the temperature swings that would cause other types of tape to fail.

  • There are foil-backed tape roll products which are labelled as « multi-purpose / hvac » and some that are specifically marked for dryer vent installation. gimmick?

Dryer vents should be sealed with foil tape as they can withstand the high temperatures encountered during machine use. Other tapes, even duct tape, are susceptible to failure under the extreme heat. Non-foil tape can also catch on fire.
