3M 7100145924 Vinyl Duct Tape Black 2in X 50yd 6.3 Mil

Product Description

The 3M 7100145924 is a black vinyl duct tape rated at 6.3 mil gauge, designed for demanding sealing, bundling, and repair applications in HVAC, construction, and industrial environments. The tape is built with a polyethylene film layer over a dense cloth scrim, backed by an aggressive rubber adhesive. This construction provides strong abrasion resistance and moisture resistance, making it suitable for use in areas exposed to humidity, dust, and mechanical wear. HVAC technicians, sheet metal workers, and general contractors install this tape where a durable, conformable cloth-reinforced tape is required.

This tape is commonly used for sealing and patching ductwork, holding insulation jacketing, and securing vapor barriers in residential and light commercial HVAC systems. Its black color makes it appropriate for exposed applications where aesthetics matter. The 2-inch width and 50-yard roll length cover standard duct seam widths and allow continuous runs without frequent re-taping. The rubber adhesive bonds well to metal, plastic, and painted surfaces under typical field conditions.

Key Features

• 6.3 mil gauge construction provides durability in high-wear environments
• Polyethylene film over dense cloth scrim for tear resistance and conformability
• Aggressive rubber adhesive bonds to metal, plastic, and painted surfaces
• Moisture and abrasion resistant for use in humid or mechanically demanding conditions
• Black finish suitable for exposed duct and surface applications
• 2-inch width x 50-yard roll length for efficient coverage on standard duct seams

Compatibility

Designed as a general-purpose industrial vinyl duct tape for HVAC ductwork sealing, insulation jacketing, vapor barrier securing, and repair applications in residential and commercial settings.

Installation Notes

Applied by hand or with a tape dispenser to clean, dry surfaces free of dust, oil, and loose debris. Surface preparation directly affects adhesive bond strength, so wipe down application surfaces before installation. No special tools or codes are required, but HVAC applications must still comply with applicable mechanical codes for duct sealing where sealant or listed tape is mandated. Do not apply to surfaces with active moisture or below the adhesive minimum service temperature.
