3M 7000122489 Foam Tape 4008 Off-white 4in X 36yd 1/8in

Product Description

The 3M 7000122489 is a double-coated, open-cell urethane foam tape sold under the 3M 4008 product line. At 1/8 inch thick, this tape features adhesive on both sides of the foam core and ships with a paper liner for handling convenience. It is engineered to bond two surfaces together while simultaneously filling gaps and conforming to irregular or uneven profiles. The foam core also provides a degree of cushioning between bonded surfaces. This roll measures 4 inches wide by 36 yards long and carries an off-white color. Fabricators, assembly technicians, HVAC installers, and general contractors use this tape in applications where a compressible, gap-filling bond layer is required.

This tape is suited for joining materials across uneven or slightly misaligned surfaces in both residential and light commercial settings. Typical applications include bonding trim, gaskets, nameplates, foam weather seal assemblies, and panel components where a conformable adhesive layer is needed. The open-cell foam construction allows the tape to compress under clamping pressure, increasing contact area across surface irregularities. It is commonly used in HVAC cabinet assembly, panel bonding, and general fabrication workflows where a permanent, load-bearing bond is not the primary requirement but gap-filling and surface conformance are.

Key Features

• Double-coated construction with adhesive on both faces for two-surface bonding
• Open-cell urethane foam core conforms to irregular and uneven surfaces
• 1/8 inch thickness provides gap-filling capability and cushioning
• Paper liner included for handling convenience and controlled application
• 4 inches wide by 36 yards long per roll
• Off-white color for discreet use in visible or semi-visible assemblies

Compatibility

Designed as a general-purpose double-coated foam tape suitable for bonding, gap-filling, and cushioning applications across a wide range of substrates including metals, plastics, and rigid foam panels in HVAC, construction, and fabrication settings.

Installation Notes

Surface preparation is critical — clean and dry mating surfaces before application to ensure full adhesive contact. Apply firm, even pressure across the tape width after positioning to maximize bond strength. In HVAC or panel assemblies, avoid stretching the tape during application, as this reduces foam thickness and may compromise the gap-fill performance. Remove the paper liner only immediately before bonding the second surface.
