3M 7000123321 Double-sided Urethane Foam Tape 1 in 36 Yd

Product Description

The 3M 7000123321 is a double-sided urethane foam tape from the 3M Series 4056 line, engineered for bonding, joining, and mounting applications where a conformable, compressible carrier is needed. The tape features a black urethane foam core measuring 1 inch wide and 1/16 inch thick (62.5 mil) wound in a continuous 36-yard roll. An acrylic adhesive is applied to both sides and backed with a paper liner for clean, controlled dispensing. With a maximum operating temperature of 220 degrees F, this tape holds up in demanding environments where heat resistance is a factor. HVAC, electrical, plumbing, and general mechanical contractors reach for this tape when securing gaskets, mounting panels, or sealing irregular surfaces.

The 3M 7000123321 is suited for residential and light commercial trade work. The urethane foam carrier conforms to uneven substrates, making it practical for mounting components to curved or textured surfaces, bonding dissimilar materials, and filling small gaps during assembly. The 1-inch width and 36-yard roll length accommodate a wide range of field applications without frequent roll changes. Trades commonly use this tape when affixing nameplates, foam gaskets, insulation strips, or lightweight brackets in confined or hard-to-reach spaces.

Key Features

• Double-sided acrylic adhesive bonds to most substrates without fasteners
• Urethane foam carrier conforms to irregular and uneven surfaces
• 1/16 inch (62.5 mil) thickness provides cushioning and gap-filling capability
• Rated to 220 degrees F maximum operating temperature
• Continuous 36-yard roll reduces mid-job roll changes
• Paper liner allows precise placement and clean peel during installation

Compatibility

Designed as a general-purpose double-sided mounting and bonding tape suitable for use across HVAC, electrical, plumbing, and mechanical applications where a conformable foam carrier with acrylic adhesive is specified.

Installation Notes

Surface preparation is critical for adhesive performance — clean and dry all bonding surfaces before application, removing grease, dust, and loose material. Apply firm pressure across the full tape length after positioning to ensure full adhesive contact. This tape is intended for general bonding and mounting tasks and should not be used as a structural fastener or primary load-bearing attachment. No special tools or licensed trade certification are required for installation, though HVAC and electrical technicians should de-energize equipment before applying tape to components inside live panels or air-handling units.
