3M 7100148743 Vinyl Duct Tape Red 2in X 50yd 6.3 Mil

Product Description

The 3M 7100148743 is a red vinyl duct tape engineered for industrial-strength sealing and repair applications in HVAC and mechanical systems. Constructed with a polyethylene film layer over a dense cloth scrim, it delivers reliable abrasion resistance and moisture resistance in demanding environments. The aggressive rubber adhesive bonds firmly to ductwork surfaces, sheet metal, and related substrates. At 6.3 mil gauge, this tape provides the thickness and conformability needed for sealing duct joints, patching vapor barriers, and general mechanical insulation work. Each roll measures 2 inches wide by 50 yards long. HVAC technicians and mechanical contractors are the primary installers.

This tape is suited for residential and commercial HVAC duct sealing, mechanical room applications, and anywhere a moisture-resistant, abrasion-resistant tape is required. The red color aids in identification on job sites where multiple tape types are in use. Typical uses include sealing duct sections, bundling insulation, and general industrial repair tasks where a heavy-gauge vinyl tape is specified. It is sold by the roll with a minimum order quantity of 24 rolls.

Key Features

• 6.3 mil gauge vinyl construction provides durability and conformability on irregular surfaces
• Polyethylene film over dense cloth scrim resists abrasion and tearing
• Aggressive rubber adhesive bonds to ductwork, sheet metal, and mechanical substrates
• Moisture-resistant construction suitable for HVAC and mechanical environments
• Red color supports job-site tape identification and color-coding practices
• 2 inches wide by 50 yards per roll for standard duct sealing coverage

Compatibility

Designed as an industrial-grade vinyl duct tape for use on HVAC sheet metal ductwork, mechanical insulation, and general industrial sealing applications.

Installation Notes

HVAC technicians and mechanical contractors apply this tape as part of duct sealing and insulation work. Surfaces should be clean, dry, and free of dust or oil before application to ensure full adhesive contact. No power shutoff is required for tape application, but standard lockout/tagout procedures should be followed if work is performed on energized duct systems. Tape applications on duct systems must comply with applicable local mechanical codes and SMACNA guidelines where enforced.
