3M 7100040610 Glass Cloth Tape 361 White 1.5in X 60yd 7.5 Mil

Product Description

The 3M 7100040610 is a white glass cloth tape sold as Model 361, designed for high-temperature masking, bundling, and sealing applications in HVAC, electrical, and industrial trade work. The tape measures 1.5 inches wide by 60 yards long and carries a gauge of 7.5 mil, giving it the thickness needed to hold up in demanding service environments. The woven glass cloth backing resists tearing, moisture, and elevated temperatures, making it a reliable choice where standard vinyl or foil tapes fall short. Licensed tradespeople and industrial maintenance technicians typically reach for this tape when a conformable, heat-resistant solution is required.

Model 361 glass cloth tape is well suited for residential and commercial HVAC duct sealing, electrical insulation, pipe and cable bundling, and general-purpose holding tasks in mechanical rooms and utility spaces. Its white finish allows for visibility in installations where identification or labeling context matters. The 60-yard roll length reduces mid-job changeovers, and the 7.5 mil thickness provides consistent laydown on metal, fiberglass, and rigid plastic substrates.

Key Features

• Woven glass cloth backing resists tearing and elevated temperatures
• 1.5-inch width and 60-yard length for extended coverage per roll
• 7.5 mil gauge provides substantial thickness for demanding hold strength
• White finish for visual clarity in bundling and identification tasks
• Sold per roll with a minimum order quantity of 24 rolls per case

Compatibility

Designed as a general-purpose glass cloth tape suitable for use on metal ductwork, fiberglass surfaces, rigid plastic, and similar substrates common in HVAC, electrical, and industrial maintenance applications.

Installation Notes

Glass cloth tape is applied by hand or with a tape dispenser and requires no special tools for most trade applications. Surfaces should be clean, dry, and free of oil or loose debris before application to ensure full adhesion. When used in HVAC or electrical contexts, verify that the tape rating is appropriate for the service temperature of the installation. Follow applicable codes, including NFPA 90A and local mechanical codes, when using tape as part of a duct sealing system.
