3M 7010373381 Urethane Foam Tape 4314 Charcoal Gray 2in X 18yd

Product Description

The 3M 7010373381 is a single-coated, open-cell urethane foam tape sold under the 3M Urethane Foam Tape 4314 product line in charcoal gray. The tape measures 2 inches wide by 18 yards long and carries a 250 mil (0.250 inch) thickness, making it one of the thicker foam tapes suited for gap-filling and sealing applications. Its soft, conformable construction allows it to conform to irregular surfaces. It is designed to seal out moisture, dust, and drafts. HVAC technicians, weatherization installers, and general contractors are the primary installers of this product.

This tape is used in residential and light commercial applications where a compressible foam seal is required. Typical scenarios include sealing gaps around duct penetrations, door and window framing, HVAC cabinet edges, and similar assemblies where air infiltration or moisture intrusion must be controlled. The open-cell urethane construction provides a resilient, conformable seal against irregular mating surfaces. Each roll weighs approximately 1.31 pounds.

Key Features

• 250 mil (0.250 inch) thickness provides substantial gap-fill capacity for irregular surfaces
• Soft, open-cell urethane foam conforms readily to uneven or textured substrates
• Single-coated construction for straightforward peel-and-stick installation
• Seals against moisture, dust, and drafts in HVAC and construction assemblies
• Charcoal gray color for low-visibility placement in mechanical and framing applications
• 18-yard roll length reduces splice frequency on longer runs

Compatibility

Designed as an OEM-style replacement and general-use foam sealing tape for HVAC cabinet closures, duct penetrations, door and window frames, and similar gap-sealing applications in residential and light commercial construction.

Installation Notes

This tape is installed by HVAC technicians, sheet metal workers, and weatherization contractors. Clean and dry the mating surface thoroughly before application to ensure full adhesive contact. Compress the foam to the manufacturer-recommended compression ratio for the intended gap size to achieve an effective seal. No special tools are required beyond a utility knife or scissors for cutting to length.
