3M 7000047491 Vinyl Foam Tape 3/8 in X 36 Yd Black

Product Description

The 3M 7000047491 is a black vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. Known in the field as 3M Vinyl Foam Tape 4516, this product is a single-coated, closed-cell foam construction that conforms to irregular surfaces for reliable adhesion. At 1/16 inch thick and 3/8 inches wide on a 36-yard roll, it delivers consistent coverage on elongated runs without mid-job splicing. HVAC technicians, sheet metal workers, insulation contractors, and general trade professionals reach for this tape when a conformable, compressible seal is needed on contoured or uneven surfaces.

This tape is suited for residential and light commercial applications where a flexible, low-profile seal is required. Typical uses include gasketing, vibration damping, weather sealing around panels and enclosures, and surface protection on metal or plastic assemblies. The closed-cell foam core resists moisture absorption, making it appropriate for both indoor and outdoor service environments where humidity or condensation is a factor.

Key Features

• Single-coated closed-cell vinyl foam construction conforms to irregular and curved surfaces
• 1/16 inch thickness provides a low-profile compressible seal without bulk
• 3/8 inches wide by 36 yards long per roll for extended coverage runs
• Black finish blends with dark substrates and reduces visible tape lines
• Resists moisture absorption due to closed-cell foam core
• Bonds to a variety of surfaces including metal, plastic, and painted substrates

Compatibility

Designed as a general-purpose conformable foam tape suitable for bonding, sealing, and gasketing applications on a variety of smooth and lightly textured surfaces common in HVAC, electrical, and general trade work.

Installation Notes

Surface preparation is critical before application — clean the substrate of oil, dust, and moisture for full adhesion. No tools beyond a utility knife or tape dispenser are typically required for cutting and applying. Apply firm hand pressure across the full length of the tape to ensure complete contact with the bonding surface. Avoid stretching the tape during application, as this can reduce long-term adhesion and seal integrity.
