3M 7100011641 Vinyl Foam Tape 2in X 36yd Black

Product Description

The 3M 7100011641 is a black vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. This single-coated, closed-cell foam tape measures 2 inches wide by 36 yards long with a thickness of 0.125 inches. The conformable vinyl construction allows it to follow irregular contours and fill gaps effectively, making it well suited for HVAC, refrigeration, plumbing, and general trade use where a durable, compressible seal is required. Each unit ships as a single roll.

This tape is commonly used in residential and light commercial applications where a flexible, closed-cell foam seal is needed around panels, ducts, doors, windows, and enclosures. Its conformable nature makes it practical for surfaces that are not perfectly flat. HVAC technicians, plumbers, and sheet metal workers frequently use this product during equipment installation and service to prevent air infiltration, vibration transfer, and moisture intrusion at joints and seams.

Key Features

Compatibility

Designed for general bonding and sealing use on a variety of surfaces including metal, painted surfaces, and rigid plastics common in HVAC, plumbing, and light commercial mechanical applications.

Installation Notes

Surface preparation is critical for adhesive performance — clean and dry the substrate before applying the tape. Ensure the application surface is free of oils, dust, and loose material. Apply firm pressure along the full length of the tape to activate the adhesive bond. Follow applicable building and mechanical codes when using tape as part of a duct sealing or enclosure application.
