3M 7000123389 Vinyl Foam Tape 0.75in X 18yd Black

Product Description

The 3M 7000123389 is a single-coated, closed-cell vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. At 0.25 inches thick, this tape offers high conformability, allowing it to compress and conform to irregular or uneven surfaces for a reliable seal. The black vinyl foam construction resists moisture and provides a durable, flexible bond. Sold as a roll measuring 0.75 inches wide by 18 yards long, it is well suited for sealing, cushioning, and gasketing tasks in HVAC, electrical, plumbing, and general trade work where a compressible, closed-cell foam tape is required.

This tape is used in residential and commercial applications where surfaces need to be bonded, sealed, or cushioned without the use of liquid adhesives. Common install scenarios include sealing around panels, ductwork edges, electrical enclosures, and pipe or conduit penetrations where a conformable foam barrier is needed. Its closed-cell foam core resists moisture absorption, making it appropriate for both interior and exterior applications in trade environments.

Key Features

• Closed-cell vinyl foam construction resists moisture and compression set
• 0.25 inches thick for high conformability on irregular surfaces
• Single-coated design for direct bonding to one substrate
• Black finish suits applications requiring a low-visibility seal
• Roll format at 0.75 inches x 18 yards for field use

Compatibility

Designed as a general-purpose vinyl foam tape suitable for bonding and sealing a variety of surfaces in HVAC, electrical, plumbing, and related trade applications.

Installation Notes

Surface preparation is critical — clean and dry the bonding surface before applying the tape to ensure full adhesive contact. Press firmly along the full length of the tape to activate the adhesive bond. For HVAC or electrical enclosure applications, verify that the tape material is appropriate for the temperature range of the installation environment. Removal and repositioning after bond set may not be possible without surface damage.
