3M 7000047496 Vinyl Foam Tape 4508 Black 0.5in X 36yd

Product Description

The 3M 7000047496 is a single-coated, closed-cell vinyl foam tape designed for bonding and sealing across a wide range of surfaces. Sold as the 3M Vinyl Foam Tape 4508 in black, this roll measures 0.5 inches wide by 36 yards long and carries a thickness of 0.125 inches. The conformable vinyl foam construction allows the tape to compress and conform to irregular or uneven surfaces, creating a reliable bond and environmental seal. HVAC technicians, plumbers, electricians, and general contractors reach for this tape when a durable, flexible, closed-cell sealing solution is needed in tight or contoured applications.

This tape is suited for residential and light commercial applications where a conformable foam seal is required. Typical uses include gasketing, vibration damping, weather sealing, and surface protection tasks found in HVAC cabinet assembly, ductwork, electrical enclosures, and plumbing rough-in work. The closed-cell foam resists moisture absorption, making it appropriate for both indoor and outdoor sealing scenarios. It is supplied in roll form for easy field application without additional tooling.

Key Features

• Closed-cell vinyl foam construction resists moisture absorption and compression set
• Conformable design seats flush against irregular or curved surfaces for consistent sealing
• Single-coated adhesive provides a secure bond to a variety of substrates
• 0.125-inch foam thickness delivers cushioning and gap-filling performance
• Black finish suits applications where tape visibility is a consideration
• 36-yard roll length reduces the need for mid-job restocking on larger installs

Compatibility

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

Installation Notes

Surface preparation is critical before application — clean the substrate free of oil, dust, and moisture to achieve full adhesive contact. No special tools are required; a roller or firm hand pressure applied along the tape length improves initial bond strength. In low-temperature environments, allow the tape and substrate to reach a moderate ambient temperature before application to ensure proper adhesion. No power shutdown or gas shutoff is required for tape application, but follow all relevant site safety protocols when working inside energized enclosures or active mechanical systems.
