3M 7000047442 Glass Cloth Tape 1 in 60 Yd White

Product Description

The 3M 7000047442 is a Series 361 glass cloth tape designed for high-temperature bundling, sealing, and seaming applications in industrial and trade environments. It is constructed with a woven glass cloth backing and a silicone adhesive that holds up in extreme thermal conditions, rated from -65 degrees F to 450 degrees F. At 7.5 mil thick with a tensile strength of 182 pounds per inch, this tape delivers the mechanical durability needed for demanding installations. It is used by HVAC technicians, electricians, and industrial maintenance professionals who need a reliable, heat-resistant tape for wire bundling and duct or component sealing.

This tape is suited for residential and commercial HVAC installations, aerospace-adjacent applications, and general industrial service where silicone adhesive performance at elevated temperatures is required. It meets FAR 25.853 flammability standards, making it appropriate for environments where fire resistance compliance is a requirement. Each roll is 1 inch wide and 60 yards long, providing ample coverage for bundling wire harnesses, sealing insulation seams, or wrapping components in high-heat zones.

Key Features

• Glass cloth backing with silicone adhesive for high-temperature performance
• Rated for use from -65 degrees F to 450 degrees F continuous service
• 182 pounds per inch tensile strength for mechanical durability
• 7.5 mil total thickness for conformability and controlled bulk
• Meets FAR 25.853 flammability standard
• Suitable for bundling, sealing, and seaming in industrial and HVAC applications

Compatibility

Designed as a general-purpose high-temperature glass cloth tape suitable for wire bundling, duct sealing, insulation seaming, and component wrapping in HVAC, electrical, and industrial maintenance applications where silicone adhesive and thermal resistance are required.

Installation Notes

This tape is typically applied by HVAC technicians or electricians as part of duct sealing, wire harness bundling, or thermal insulation work. Surfaces should be clean, dry, and free of oils or loose debris before application to ensure proper adhesion. When used in high-temperature zones, confirm that surrounding materials are also rated for the operating temperature range. Follow all applicable NEC and local code requirements when routing or bundling electrical conductors.
