Spiral Duct Systems

When planning a ductwork project there is nothing more efficient or easy to install than a spiral duct system from Macy Industries. We are proud to offer the highest quality materials and construction to ensure your system is leak-free, with convenient fabrication options to make assembly and installation simple.

Self-Sealing Spiral Duct Fittings

Our self-sealing spiral duct fittings utilize a soft rubber o-ring on every connection which allows each end to smoothly slide into place and form a tight seal when the duct connection is made. On top of being quicker and easier to assemble, these self-sealing gaskets are more leak-proof and energy efficient than foil, tape or putty.

The best fitting in the industry: Designed with your needs in mind!

  • Save 25% on installation costs versus using duct seal or foil
  • Ensure tighter seals, cleaner air quality and energy savings
  • Ideal for exposed spiral projects your finished duct work is clean and void of sealer or tape

This tight seal ensures cleaner air quality and energy efficiency.
