3M 7000124257 Performance Plus Duct Tape 24mm X 54.8m

Product Description

The 3M 7000124257 is a Performance Plus Duct Tape in slate blue, part of 3M's professional-grade 8979 series. This tape is engineered for demanding HVAC duct sealing, bundling, and repair applications where a strong, conformable tape is required. It features a reinforced backing that resists moisture and holds firmly to metal, flex duct, and rigid ductboard surfaces. At 24mm wide and 54.8 meters long per roll, it provides extended run length suited to production-paced field work. Licensed HVAC technicians and sheet metal contractors are the primary installers of this product in both residential and light commercial settings.

This tape is used for sealing and patching HVAC ductwork, including connections at fittings, plenums, and transitions. It is also appropriate for bundling pipe insulation, securing vapor barriers, and general mechanical insulation work. The 24mm width makes it well suited for narrower seams and detail work in tight installations. The slate blue color allows for easy visual identification on completed duct assemblies. It is sold as a single roll, with a minimum order quantity of 48 rolls per case.

Installation Notes

This tape is typically applied by licensed HVAC technicians or sheet metal workers during duct fabrication or repair.
