3M 7000123394 Urethane Foam Tape 1in X 18yd 250 Mil

Product Description

The 3M 7000123394 is a single-coated, open-cell urethane foam tape designed for sealing applications in residential and commercial construction and mechanical systems. At 250 mil (approximately 0.25 inches) thick, it is soft and conformable, allowing it to compress evenly against irregular surfaces. The tape ships in a 1-inch-wide by 18-yard roll and is finished in charcoal gray. It seals out moisture, dust, and drafts, making it a practical choice wherever a compressible, moisture-resistant barrier is needed along joints, gaps, or panel edges.

This tape is suited for HVAC duct sealing, panel gasketing, door and window perimeter sealing, and general mechanical insulation work. Installers use it in both new construction and retrofit scenarios where a soft, conformable foam seal is required along mating surfaces. Its open-cell urethane construction allows the material to conform to surface irregularities without adhesive bridging, providing consistent contact along the full length of the joint.

Key Features

• Open-cell urethane foam construction for soft, conformable compression
• 250 mil thickness (approximately 0.25 inches) provides substantial gap fill
• Single-coated adhesive backing for direct surface application
• Seals against moisture intrusion, dust, and air drafts
• Charcoal gray finish blends with common mechanical and construction substrates
• 1-inch width by 18-yard length per roll for standard joint coverage

Compatibility

Designed as an OEM-style sealing tape for use in residential and commercial HVAC, construction, and general mechanical applications requiring a compressible urethane foam gasket or draft seal.

Installation Notes

This tape is applied by trade professionals including HVAC technicians, insulation installers, and general contractors. Clean and dry the mating surface before application to ensure full adhesive contact. Avoid stretching the tape during application, as this reduces effective thickness and sealing performance. Follow applicable building and mechanical codes for air sealing and moisture management requirements.
