3M 7000047494 Vinyl Foam Tape 0.25in X 36yd Black

Product Description

The 3M 7000047494 is a black vinyl, single-coated, closed-cell foam tape designed for bonding and sealing applications across a wide range of surfaces. At 0.125 inches thick, the conformable foam construction allows it to compress and fill irregular gaps, creating a reliable seal against air, moisture, and dust. Sold as a single roll measuring 0.25 inches wide by 36 yards long, this tape is well suited for HVAC, plumbing, electrical, and general trade work where a flexible, compressible seal is required. Installation requires no special tools and the pressure-sensitive adhesive bonds on contact.

This tape is commonly used in residential and light commercial applications where a durable, weatherproof seal is needed on metal, plastic, wood, or painted surfaces. Typical uses include gasketing around panels and enclosures, vibration dampening, gap sealing around ducts and fittings, and surface protection during assembly. The closed-cell foam resists moisture absorption, making it appropriate for both interior and exterior installations. HVAC technicians, electricians, and plumbers regularly stock this format for on-the-job sealing tasks.

Key Features

• Single-coated closed-cell vinyl foam construction conforms to irregular surfaces
• 0.125 inches thick for reliable gap filling and compression sealing
• Black finish suitable for both visible and concealed installations
• Pressure-sensitive adhesive bonds on contact without primers on most surfaces
• Closed-cell foam resists moisture absorption for interior and exterior use
• 36-yard roll length reduces mid-job splicing on larger installs

Compatibility

Designed as a general-purpose bonding and sealing tape compatible with metal, plastic, wood, and painted surfaces in residential and light commercial trade applications.

Installation Notes

Surface should be clean, dry, and free of oils or loose material before application. Apply firm hand pressure along the full length of the tape to ensure full adhesive contact. For HVAC or enclosure sealing work, confirm the tape width and thickness provide adequate compression for the gap being sealed. No special tools or licensed trade certification are required for standard tape installation, though local codes may govern specific sealing applications on gas or refrigerant-carrying systems.
