3M 7000123390 Vinyl Foam Tape 4726 Black 1in X 36yd

Product Description

The 3M 7000123390 is a single-coated, closed-cell vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. Sold as the 4726 Black variant, this tape measures 1 inch wide by 36 yards long and is 0.0625 inches (1/16 inch) thick. Its conformable vinyl foam construction allows it to follow irregular or uneven surfaces, maintaining consistent contact and seal integrity. HVAC technicians, installers, and general trade professionals use this tape where a compressible, conformable seal is needed between dissimilar materials or at joints and seams.

This tape is suited for residential and light commercial applications where a flexible, black vinyl foam seal is required. Common install scenarios include sealing gaps at duct joints, weather sealing around panels, vibration dampening between components, and surface bonding where a compressible adhesive layer improves contact. The closed-cell foam core resists moisture absorption, making it appropriate for environments where incidental water exposure is expected.

Key Features

• Closed-cell vinyl foam construction resists moisture absorption
• Single-coated adhesive bonds to a variety of surfaces without additional fasteners
• Conformable design follows irregular and uneven surfaces for consistent sealing
• 0.0625-inch (1/16 inch) thickness provides compressible cushioning at joints and seams
• Black finish blends with standard duct and mechanical enclosure surfaces
• 36-yard roll length reduces roll changes on larger jobs

Compatibility

Designed as a general-purpose vinyl foam sealing and bonding tape suitable for use on a variety of substrate surfaces in HVAC, construction, and general mechanical applications where a conformable, single-coated closed-cell foam tape is specified.

Installation Notes

Surface preparation is critical before application — clean and dry the substrate to remove dust, oil, and loose material for maximum adhesion. Apply firm pressure along the full length of the tape after placement to ensure complete adhesive contact. In HVAC duct applications, consult local mechanical codes for approved sealing methods, as foam tape may be used in conjunction with other listed sealants depending on jurisdiction. Do not stretch the tape during application, as this can reduce long-term bond strength.
