Seal, join, and repair HVAC ductwork with confidence. FindTape carries UL 181 listed foil, metalized cloth, and butyl tapes built for flex duct, rigid metal duct, and duct board on every job.
Every solid HVAC system depends on tight seams and secure joints, and that is exactly what our HVAC duct tape lineup delivers. From flexible duct connections to rigid metal trunk lines, these tapes create airtight, moisture resistant seals that keep conditioned air where it belongs instead of leaking into attics, crawl spaces, or walls.
Choose from UL 181 listed foil tapes for code compliant flex duct and duct board sealing, tough metalized cloth tape for contractor grade seaming, and foil mastic butyl tape for outdoor and below grade joints that need a permanent, weatherproof bond. Need something for higher heat? Our high temperature flue tape handles hot exhaust and flue connections without breaking down.
These tapes are trusted by HVAC pros, contractors, and DIYers alike for new installations, repairs, and retrofits. They stick fast to aluminum, galvanized steel, fiberglass duct board, and insulated flex duct, and most go on with just hand pressure, no special tools needed.
