3M 7000047497 Vinyl Foam Tape 4508 Black 1in X 36yd

Product Description

The 3M 7000047497 is a black vinyl closed-cell foam tape designed for bonding and sealing applications across a range of trade and industrial surfaces. Sold as a 1-inch-wide by 36-yard roll, the tape is 0.125 inches thick and features a single-coated acrylic adhesive on a conformable, closed-cell vinyl foam carrier. Its closed-cell construction resists moisture absorption, making it suitable for sealing gaps and isolating surfaces where air or water infiltration is a concern. HVAC technicians, plumbers, electricians, and general contractors use this tape for gasketing, vibration dampening, and surface protection tasks in both residential and light commercial settings.

This tape is well suited for applications requiring a conformable, compressible seal on irregular or slightly uneven surfaces. Common uses include sealing around mechanical penetrations, cushioning between components, and bonding trim or panels where a flexible, weather-resistant barrier is needed. The 36-yard roll length supports extended runs without splicing, making it practical for larger sealing jobs on ductwork, cabinets, enclosures, or framing assemblies.

Key Features

• Closed-cell vinyl foam construction resists moisture absorption and air infiltration
• Conformable carrier adapts to irregular or uneven mating surfaces
• 1 inch wide by 36 yard roll for extended coverage without splicing
• 0.125 inch thickness provides compressible cushion and gap fill
• Single-coated adhesive bonds to a variety of substrates including metal, wood, and plastic
• Black finish suits concealed or low-visibility installations

Compatibility

Designed as a general-purpose single-coated vinyl foam tape suitable for bonding and sealing applications on a wide range of surfaces in HVAC, plumbing, electrical, and general construction trades.

Installation Notes

Surface preparation is critical — clean, dry, and degrease the substrate before application to ensure full adhesive contact. Apply firm pressure along the entire length of the tape to activate the adhesive bond. For HVAC or mechanical sealing use, verify that the tape is rated for the operating temperature range of the application before installation. No special tools are required, but a roller or seam tool improves bond consistency on larger runs.
