3M 7000133168 Silicone Self-fusing Electrical Tape 1in X 30ft

Product Description

The 3M 7000133168 is a self-fusing silicone electrical tape in a heavy duty triangular (HDT) format, measuring 1 inch wide by 30 feet long per roll. It is designed for high-performance insulation, sealing, and splicing on electrical conductors, cable bundles, and exposed wiring in demanding environments. The self-fusing construction means the tape bonds to itself without adhesive, creating a void-free, moisture-resistant wrap. Licensed electricians and trade professionals typically install this tape when a durable, heat-resistant insulating layer is required on wire splices, terminal connections, and cable repairs.

This tape is suited for both residential and commercial electrical applications where standard vinyl tapes fall short. Common use cases include insulating high-voltage splices, sealing cable jacket repairs, wrapping exposed conductors in wet or high-temperature areas, and protecting connections on motor leads and control wiring. The triangular roll format reduces uneven stretching during application and helps maintain consistent tape tension across the wrap.

Key Features

• Self-fusing silicone construction bonds to itself with no adhesive residue
• Heavy duty triangular roll format promotes even stretch and consistent layering
• 1 inch wide by 30 feet long per roll provides substantial coverage per unit
• Silicone base material offers strong resistance to moisture, heat, and UV exposure
• Void-free wrap reduces risk of tracking or moisture ingress at splice points

Compatibility

Designed as an OEM-style general-purpose silicone electrical tape suitable for use on standard electrical conductors, cable bundles, and wire splices in commercial and residential installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before applying tape to any conductor or splice. Stretch the tape uniformly during application and overlap each layer by at least half the tape width to ensure a complete self-fusing bond. Avoid applying over contaminated, oily, or wet surfaces that may prevent proper fusion.
