3M 7000005814 Glass Cloth Electrical Tape 0.5x66ft White

Product Description

The 3M 7000005814 is a white glass cloth electrical tape engineered for high-temperature insulation and bundling applications in electrical and HVAC systems. It uses a rubber thermosetting adhesive that bonds reliably under sustained heat, making it suitable for motor lead wire insulation, coil wrapping, and transformer applications. The roll measures 0.5 inches wide by 66 feet long, giving technicians ample material per roll for repetitive wrapping tasks. The glass cloth backing resists tearing and holds dimensional stability under thermal cycling, which is critical in environments where standard vinyl tapes would soften or fail.

This tape is commonly used by electricians, HVAC technicians, and motor rewind shops working on residential and commercial equipment. Typical applications include insulating motor leads, securing and protecting wire bundles routed through high-heat zones, and wrapping coil ends on transformers and solenoids. It performs in environments where operating temperatures exceed the rating of standard electrical tapes. The white color aids visual identification in multi-tape wiring assemblies.

Key Features

• Glass cloth backing provides tear resistance and dimensional stability under thermal cycling
• Rubber thermosetting adhesive maintains bond at elevated operating temperatures
• 0.5 inch width suits motor lead wrapping and precision bundling tasks
• 66-foot roll length reduces roll changeovers during production or service work
• White color aids visual differentiation in multi-layer or multi-tape assemblies
• Sold in cases of 50 rolls for shop stock and high-volume service operations

Compatibility

Designed as an OEM-style insulating tape for use in residential and commercial electrical and HVAC motor applications where high-temperature glass cloth tape is specified.

Installation Notes

This tape is applied by licensed electricians and HVAC technicians during motor service, coil repair, and wire insulation tasks. De-energize all equipment and follow applicable NFPA 70 (NEC) lockout/tagout procedures before handling any exposed conductors or motor leads. Apply the tape with consistent tension to prevent air pockets or gaps in the insulation wrap. Do not stretch the glass cloth backing aggressively during application, as this can compromise the adhesive bond and backing integrity.
