3M 7000048431 Foam Tape 4008 Off-white 2in X 36yd 1/8in

Product Description

The 3M 7000048431 is a double coated, open-cell urethane foam tape designed to bond, seal, and fill gaps across a wide range of trade and industrial applications. At 1/8 inch thick, the foam core conforms to irregular and uneven surfaces, creating a reliable bond line where rigid tapes would leave voids. Both faces carry a pressure-sensitive adhesive, and a paper liner protects the second adhesive face until the tape is ready to apply. HVAC technicians, sheet metal workers, and general contractors reach for this tape when mounting panels, gasketing enclosures, or cushioning components against vibration.

This tape is well suited for residential and light commercial applications where gap-filling and cushioning are needed alongside a structural bond. Typical uses include mounting nameplates and trim pieces, sealing irregular cabinet joints, and attaching foam weatherstripping backings. The off-white foam blends with common equipment finishes. Each roll measures 2 inches wide by 36 yards long, providing substantial coverage per roll. The tape ships in a minimum quantity of 6 rolls per order.

Key Features

• Open-cell urethane foam core at 1/8 inch thickness conforms to irregular and uneven surfaces
• Double coated construction — adhesive on both faces eliminates need for additional bonding agents
• Paper liner protects the second adhesive face for controlled, clean application
• Provides cushioning and vibration dampening in addition to bonding
• Off-white color suits common equipment and panel finishes
• 2 inches x 36 yd roll format offers generous coverage per unit

Compatibility

Designed as an OEM-style and general-purpose replacement foam bonding tape for HVAC enclosures, sheet metal assemblies, electrical panels, and similar trade applications requiring gap-filling adhesive mounting.

Installation Notes

Surface preparation is critical — clean and dry all bonding surfaces before applying the tape to achieve full adhesive contact. Remove the paper liner from one face, position the tape, press firmly across the full bond area, then remove the second liner before mating the opposing surface. Allow adequate dwell time under pressure for the adhesive to reach full bond strength before placing the assembly into service. This tape is intended for professional installation in appropriate trade applications.
