3M 7000047441 Glass Cloth Tape 361 White 3/4 in X 60 Yd

Product Description

The 3M 7000047441 is a white glass cloth tape engineered for demanding high-temperature applications in HVAC, electrical, and industrial settings. Built on a fiberglass-reinforced backing 7.5 mil thick, it delivers the tensile strength needed for bundling wire harnesses, securing insulation, and protecting components exposed to extreme heat. The silicone adhesive system provides reliable holding power with clean removal across a broad temperature range, rated from -65 degrees F to 450 degrees F continuously and up to 550 degrees F intermittently. Licensed tradespeople working on duct systems, high-voltage wiring, or industrial equipment will find it suited to jobs where conventional rubber- or acrylic-based tapes fail.

This tape is used in residential and commercial HVAC installations for securing fiberglass duct wrap, thermal insulation jacketing, and wire harness protection near heat sources. Electrical contractors apply it for bundling conductors in environments with sustained elevated temperatures. It is also used in industrial maintenance and OEM manufacturing where abrasion resistance and clean removal are required after service. The 3/4 inch width and 60-yard roll length make it practical for extended runs or repetitive wrapping tasks on smaller-diameter components.

Key Features

• Glass cloth backing resists abrasion and delivers high tensile strength for bundling and harnessing
• Silicone adhesive rated for continuous use from -65 degrees F to 450 degrees F
• Handles intermittent temperatures up to 550 degrees F or higher depending on heat source type and duration
• Clean removal leaves minimal residue across a wide temperature range
• 7.5 mil total thickness provides durability without excessive bulk
• White finish aids visual identification in multi-tape or color-coded installations

Compatibility

Designed as an OEM-style and field-service replacement tape for high-temperature bundling, harnessing, and thermal insulation applications in HVAC, electrical, and industrial environments.

Installation Notes

Apply to clean, dry surfaces free of oils, dust, and loose material for maximum adhesion. HVAC technicians and electricians should power down or de-energize systems before applying tape near live wiring or active heat sources. When used in duct or insulation applications, follow applicable mechanical and energy codes for your jurisdiction. Avoid stretching the tape during application, as this can reduce long-term adhesion on curved or irregular surfaces.
