Industrial-grade duct tape for demanding sealing

The 3M 8979 is a blue polyethylene-coated cloth tape built to industrial grade. It measures 96 mm wide by 60 yards long with a 12.1 mil thickness. Rubber adhesive on one side delivers 48 oz/in adhesion and 36 lb-in tensile strength. It suits electricians and maintenance crews who need reliable holding power for bundling, sealing and temporary repairs.

Temperature and surface limits of the rubber

The tape is rated for performance up to 200 degrees Fahrenheit. Beyond that temperature the rubber adhesive can soften and lose grip. It meets UL 723 for surface burning characteristics. The cloth scrim resists tearing, yet the tape remains hand-tearable. It is not designed for permanent structural bonds or continuous outdoor exposure where UV degrades the polyethylene backing.

Upgrades from general-purpose cloth tapes

This roll replaces lighter utility-grade duct tapes that use thinner backings and weaker adhesives. The jump is worth it when the job demands higher tensile strength, consistent adhesion across temperature swings or a UL 723 listing for code compliance. It is not for buyers who need a permanent outdoor membrane, a high-temperature foil tape or a specialised electrical insulating tape.

Questions about this item

Should I pick the 60-yard roll or a shorter length?

This listing is a single 60-yard continuous roll, 96 mm wide and 12.1 mil thick, so choose it when you need that full length for larger jobs.

How does the 12.1 mil thickness perform on a real job site?

At 12.1 mil the tape provides industrial-grade durability with 36 lb-in tensile strength and 48 oz/in adhesion, holding firmly on ducts, cables and rough surfaces.

What does the UL 723 rating actually limit in practice?

UL 723 confirms the tape meets surface-burn characteristics for building codes, while the rubber adhesive is rated up to 200 degrees F for sustained heat exposure.
