3M 7100097928 Urethane Foam Tape 4318 Charcoal Gray 1/4in X 36yd

Product Description

The 3M 7100097928 is a single-coated, open-cell urethane foam tape sold under the 3M Urethane Foam Tape 4318 product line in charcoal gray. The tape measures 1/4 inches wide by 36 yards long and is 1/8 inch thick. Its soft, conformable construction allows it to compress and conform against irregular surfaces, creating a reliable seal. Designed to block moisture, dust, and drafts, this tape is well suited for weatherstripping, gap sealing, and light cushioning applications in both residential and light commercial environments. Installation requires no special equipment beyond a clean, dry surface and standard cutting tools.

This tape is a practical choice for HVAC technicians, contractors, and maintenance professionals sealing gaps around ductwork, panels, doors, windows, and enclosures. The open-cell urethane foam construction provides good conformability against uneven substrates. The charcoal gray color blends discreetly into most mechanical and building assemblies. It is sold in individual rolls and is suitable for jobs requiring a flexible, compressible foam seal where a single-adhesive-side tape is appropriate.

Key Features

• Open-cell urethane foam construction — soft and conformable against irregular surfaces
• Single-coated adhesive — one bonding side for straightforward surface attachment
• 1/8 inch thickness provides consistent compression and gap fill
• Seals out moisture, dust, and drafts in weatherstripping and panel sealing applications
• Charcoal gray color for discreet installation in mechanical assemblies
• 36-yard roll length reduces mid-job splicing on larger sealing runs

Compatibility

Designed as a general-purpose foam sealing tape suitable for use on doors, windows, ductwork panels, electrical enclosures, and similar surfaces where a compressible, single-coated foam tape is required.

Installation Notes

Surface must be clean, dry, and free of grease or loose material before applying the tape. Cut to length with a utility knife or scissors and press firmly along the full bonding surface to ensure good adhesive contact. Power down or de-energize any electrical enclosure before applying tape near live components. Follow all applicable building and mechanical codes for the specific sealing or insulation application.
