3M 7000123396 Urethane Foam Tape 3/8 in 9 Yd Charcoal Gray

Product Description

The 3M 7000123396 is a single-coated, open-cell urethane foam tape designed for sealing applications in residential and commercial construction and mechanical systems. At 3/8 inches thick, the charcoal gray foam is soft and conformable, allowing it to compress against irregular surfaces and create a reliable barrier against moisture, dust, and drafts. Sold in a 9-yard roll, it suits runs requiring a continuous, flexible seal without adhesive bridging or hard edges. HVAC technicians, insulators, and general contractors reach for this tape when standard closed-cell options lack the conformability a joint or gap demands.

This tape is used in duct sealing, door and window perimeter sealing, equipment cabinet gasketing, and pipe insulation terminations. Its open-cell urethane construction compresses readily against uneven mating surfaces, making it a practical choice for retrofit work where surfaces are not perfectly parallel. The charcoal gray color blends with metal ductwork and equipment housings in light-commercial and residential HVAC installations.

Key Features

• Open-cell urethane foam construction provides high conformability to irregular surfaces
• 3/8 inches thick for substantial gap-filling and compression sealing
• Single-coated adhesive backing for straightforward application to one mating surface
• Seals against moisture, dust, and drafts
• 9-yard roll length reduces splices on longer sealing runs
• Charcoal gray finish suits metal duct and equipment housing applications

Compatibility

Designed for general-purpose foam tape sealing applications in HVAC, construction, and light industrial environments where a conformable, single-coated open-cell foam is required.

Installation Notes

Clean and dry the mating surface thoroughly before applying the tape to ensure full adhesive contact. Cut to length with a utility knife or scissors. Apply firm hand pressure along the full length of the tape after placement to seat the adhesive. Follow applicable building and mechanical codes when using foam tape as a component of duct sealing or weatherization assemblies.
