3M 7100006373 Urethane Foam Tape 0.5in X 18yd 250 Mil

Product Description

The 3M 7100006373 is a single-coated, open-cell urethane foam tape designed for sealing and cushioning applications in residential and commercial construction and HVAC work. The tape measures 0.5 inches wide by 18 yards long with a thickness of 250 mil (approximately 0.25 inches). Its soft, conformable urethane foam construction allows it to compress and conform to irregular surfaces, creating an effective barrier against moisture, dust, and drafts. Charcoal gray in color, this tape is sold by the roll and is a practical choice for trade professionals handling weatherstripping, gap sealing, and HVAC duct or panel sealing tasks.

This foam tape is suited for use in residential and light commercial settings where a flexible, compressible seal is needed. Common applications include sealing gaps around doors, windows, HVAC panels, ductwork penetrations, and other areas where moisture infiltration or air leakage is a concern. The open-cell urethane foam provides a conformable fit against uneven or textured substrates, making it a useful material for installers working with sheet metal cabinets, framing, or mechanical enclosures.

Key Features

• Single-coated open-cell urethane foam construction for conformable sealing
• 250 mil (0.25 inches) thick for effective gap filling and compression sealing
• Seals against moisture, dust, and air drafts
• 0.5 inches wide by 18 yards per roll for extended coverage
• Charcoal gray color for low-visibility installation in mechanical and HVAC applications

Compatibility

Designed as a general-purpose urethane foam sealing tape suitable for use on metal, wood, and rigid plastic substrates commonly found in HVAC, construction, and mechanical installation work.

Installation Notes

This tape is typically applied by HVAC technicians, insulators, or general contractors during rough-in or finishing stages of installation. Surfaces should be clean, dry, and free of oils or loose debris before application to ensure proper adhesion. No special tools are required, though a sharp utility knife or tape dispenser aids in clean cuts. Follow applicable building and energy codes when using foam tape as part of an air or moisture barrier assembly.
