3M 7000144749 Red Duct Tape 48mm X 54.8m 7.7 Mil

Product Description

The 3M 7000144749 is an industrial-strength duct tape built for demanding sealing and bundling applications. Constructed with a polyethylene film over a dense cloth scrim and bonded with an aggressive rubber adhesive, this tape delivers reliable abrasion and moisture resistance. It measures 48mm wide with a 54.8-meter roll length and features a 7.7 mil gauge thickness. The combination of a reinforced scrim backing and high-tack rubber adhesive makes it suitable for heavy-duty work in mechanical, HVAC, and general industrial settings.

This tape is designed for use in commercial and industrial environments where standard consumer-grade tape fails under exposure to moisture, abrasion, or repeated mechanical stress. Typical applications include ductwork sealing, bundling, patching, and temporary repairs on job sites. The red color aids in identification and can help differentiate tape runs in multi-trade installations. Sold in rolls, it is well suited for HVAC technicians, sheet metal contractors, and facilities maintenance crews.

Key Features

• 7.7 mil gauge thickness for heavy-duty durability
• Polyethylene film over dense cloth scrim backing for tear resistance and abrasion protection
• Aggressive rubber adhesive for strong, reliable bond on common duct and mechanical surfaces
• Moisture-resistant construction suitable for exposed or damp environments
• Red color for easy visual identification in multi-trade or color-coded installations
• 48mm width and 54.8m roll length for extended coverage per roll

Compatibility

Designed as an industrial-grade replacement for standard duct tape in HVAC, sheet metal, and general mechanical applications requiring abrasion and moisture resistance.

Installation Notes

This tape is typically applied by HVAC technicians or sheet metal workers during ductwork fabrication, sealing, or repair. Surfaces should be clean, dry, and free of oil or loose debris before application to ensure full adhesive contact. Apply firm pressure along the tape length to activate the rubber adhesive and eliminate air pockets. Consult local mechanical codes for approved taping methods on pressure-rated duct systems.
