3M 7000123392 Urethane Foam Tape 3/4in X 9yd Charcoal Gray

Product Description

The 3M 7000123392 is a single-coated, open-cell urethane foam tape designed for sealing applications in construction, HVAC, and general building maintenance. At 3/8 inches thick, the soft, conformable foam compresses easily against irregular surfaces to form a reliable barrier against moisture, dust, and drafts. The charcoal gray finish suits concealed or semi-exposed installations. Sold as a 3/4-inch-wide by 9-yard roll, it is sized for runs around door and window frames, panel gaps, and HVAC cabinet seams where a flexible, compressible seal is required.

This tape is well suited for residential and light commercial applications where gasketing or sealing with a thin profile is needed. HVAC technicians use it to seal cabinet joints, access panel edges, and duct penetrations. Contractors and building maintenance professionals reach for it when sealing around framing, fixtures, or conduit entry points. The open-cell urethane construction allows the foam to conform to uneven or textured surfaces without bridging gaps.

Key Features

• Open-cell urethane foam construction conforms to irregular and textured surfaces
• 3/8 inches thick for compressible, low-profile sealing
• Seals against moisture infiltration, dust, and drafts
• Single-coated adhesive backing for direct surface application
• Charcoal gray color for low-visibility installations
• 3/4-inch width suits narrow seams, panel edges, and frame perimeters

Compatibility

Designed as an OEM-style replacement and general-purpose sealing tape for residential and commercial HVAC cabinet seams, door and window framing gaps, and building envelope penetration points.

Installation Notes

Surface preparation is critical — clean and dry the substrate before applying the tape to ensure full adhesive contact. Cut to length with a utility knife or scissors; avoid stretching the foam during application as this reduces effective thickness. For HVAC cabinet sealing, power down the unit before accessing panels. Follow applicable building and mechanical codes for air-sealing requirements in conditioned spaces.
