3M 7000001231 Extra Heavy Duty Duct Tape 72mm X 54.8m

Product Description

The 3M 7000001231 is an extra heavy duty duct tape engineered for industrial and demanding trade applications. Built on a dense cloth scrim with a polyethylene film backing and an aggressive rubber adhesive, it delivers high holding power on most surfaces. The tape measures 72mm wide by 54.8m long per roll and comes in at 10.7 mils thick, providing a tough, resilient bond in harsh conditions. Abrasion and moisture resistance make it well suited for environments where standard duct tapes fall short. Individual roll wrap preserves roll integrity between uses, reducing waste on job sites. HVAC technicians, sheet metal workers, and general contractors reach for this tape when the application demands industrial-grade performance.

This tape is used across residential, commercial, and industrial settings wherever a high-strength, moisture-resistant duct tape is required. Common applications include sealing, bundling, patching, and repair work on duct systems, equipment housings, and general mechanical assemblies. The easy-tear design speeds installation without the need for a cutting tool, and the tack-free edges keep rolls clean and ready to apply. It performs in temperature environments up to 200 degrees F, making it appropriate for use near heat-generating mechanical equipment.

Key Features

• 10.7 mil total thickness for industrial-grade durability and tear resistance
• Aggressive rubber adhesive bonds to most surfaces with 61 oz. per inch width adhesion to steel
• Tensile strength of 32 lbs. per inch width handles demanding mechanical stress
• Polyethylene film over dense cloth scrim provides abrasion and moisture resistance
• Easy-tear design eliminates the need for scissors or a knife on the job site
• Individual roll wrap maintains roll integrity and reduces material waste

Compatibility

Designed as an industrial-strength duct tape suitable for sealing, patching, and bundling applications on ductwork, mechanical assemblies, and general construction surfaces where high adhesion and moisture resistance are required.

Installation Notes

Surface should be clean, dry, and free of dust or oil before application for best adhesive performance. Apply with firm hand pressure across the full width of the tape to ensure full contact. This tape is intended for use up to 200 degrees F and should not be used in continuous high-heat or open-flame environments beyond its rated temperature range. No special tools are required for installation; the easy-tear backing allows field cutting by hand.
