3M 7000048512 Vinyl Foam Tape Black 1 in X 36 Yd

Product Description

The 3M 7000048512 is a single-coated, closed-cell vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. Known in the field as 3M Vinyl Foam Tape 4718, this black tape measures 1 inch wide by 36 yards long and is 0.125 inches thick. Its highly conformable construction allows it to conform tightly to irregular surfaces, making it a reliable choice for gap filling, cushioning, and environmental sealing tasks. HVAC technicians, sheet metal workers, and maintenance professionals regularly reach for this tape when a compressible, durable seal is needed in confined or contoured areas.

This tape is suited for residential and commercial applications where a conformable, closed-cell foam seal is required. Common use cases include sealing around ductwork components, panels, enclosures, and trim where surface irregularities would compromise a rigid seal. Its vinyl foam construction resists moisture and provides consistent compression across the bond line. The single-coated format means one face carries the adhesive while the opposite face remains exposed, which fits standard mounting and sealing configurations.

Key Features

• Closed-cell vinyl foam construction resists moisture intrusion and compression set
• Highly conformable — follows irregular and contoured surfaces
• Single-coated adhesive on one face for bonding and sealing
• 0.125 inch foam thickness provides consistent gasketing performance
• Black finish suits low-visibility mechanical and HVAC installations
• 1 inch width by 36 yard length per roll for versatile job-site use

Compatibility

Designed for bonding and sealing to a variety of surfaces including metals, plastics, and painted substrates in HVAC, electrical, and general maintenance applications.

Installation Notes

Surface preparation is critical — clean the substrate free of dust, oil, and moisture before application to ensure full adhesive contact. Apply firm, even hand pressure across the full length of the tape to achieve proper bonding. For HVAC sealing applications, verify the surface temperature is within the adhesive operating range before installation. Remove any existing foam or tape residue from the mating surface before applying a new strip.
