3M 7000048814 Duct Tape Silver 9.0 Mil 24mm X 54.8m

Product Description

The 3M 7000048814 is an industrial-strength duct tape engineered for demanding applications where abrasion resistance and moisture protection are required. The construction layers a polyethylene film over a dense cloth scrim and bonds it with an aggressive rubber adhesive, resulting in a 9.0 mil gauge tape that holds firmly on rough, irregular, or wet surfaces. At 24mm wide and 54.8 meters per roll, this tape is well suited for HVAC duct sealing, bundling, patching, and general mechanical work where a standard consumer tape would fail under stress.

This tape is used in residential and light commercial settings by HVAC technicians, plumbers, electricians, and general maintenance professionals. Its moisture-resistant polyethylene facing makes it appropriate for sealing flexible ductwork, wrapping pipes, securing insulation, and temporary repairs in environments with exposure to humidity or condensation. The silver finish is consistent with standard duct tape color coding used across the trades.

Key Features

• 9.0 mil total thickness for durability in heavy-duty mechanical and HVAC applications
• Polyethylene film over dense cloth scrim construction resists tearing and abrasion
• Aggressive rubber adhesive maintains bond on rough and uneven surfaces
• Moisture-resistant facing suitable for humid or condensation-prone environments
• 24mm width fits standard hand-held tape dispensers
• 54.8-meter roll length reduces mid-job roll changes on large projects

Compatibility

Designed as a general-purpose industrial duct tape for use across HVAC, plumbing, electrical, and maintenance applications requiring an abrasion-resistant and moisture-resistant adhesive tape.

Installation Notes

Applied by hand or with a standard tape dispenser; no special tools are required. Surfaces should be clean, dry, and free of dust or grease before application to ensure full adhesive contact. For HVAC duct sealing, consult local mechanical codes to confirm whether duct tape alone meets code requirements for the specific duct type and pressure class. Do not use as a primary structural fastener or in continuous high-heat environments above the rated temperature of the adhesive.
