3M 7010373384 Urethane Foam Tape 4318 Charcoal Gray 2in X36yd

Product Description

The 3M 7010373384 is a single-coated, open-cell urethane foam tape sold under the 3M Foam Tape 4318 product line in charcoal gray. Measuring 2 inches wide by 36 yards long and 0.125 inches thick, this soft, conformable tape is engineered to seal out moisture, dust, and drafts in gap-filling and weathersealing applications. Its open-cell urethane construction allows the tape to compress and conform to irregular surfaces, making it suitable for professional installation in HVAC, construction, and general trade settings. Each unit is sold as a roll and weighs 1.67 pounds.

This tape is well suited for residential and light commercial applications where a flexible, compressible seal is required. Common uses include sealing gaps around ductwork penetrations, door and window perimeters, panel joints, and similar areas where air infiltration, dust intrusion, or moisture entry must be controlled. HVAC technicians, sheet metal installers, and general contractors routinely use this product during equipment installation and building envelope work.

Key Features

• Open-cell urethane foam construction conforms to irregular and uneven surfaces
• Single-coated design for straightforward surface bonding
• 0.125 inch thickness provides compressible gap-filling performance
• Seals against moisture, dust, and draft infiltration
• Charcoal gray color for discreet installation in visible or semi-visible locations
• 36-yard roll length reduces splicing frequency on longer runs

Compatibility

Designed as a general-purpose urethane foam sealing tape suitable for use on metal, wood, and rigid plastic substrates in HVAC, construction, and related trade applications where a compressible foam seal is required.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or general contractors using standard hand tools for cutting and application. Ensure the substrate surface is clean, dry, and free of oils or loose material before applying the tape to achieve proper adhesion. Where building code compliance is a factor, verify that the tape meets applicable local energy or fire codes before use in concealed or plenum-adjacent spaces.
