3M 7000145519 Heat Shrinkable Cable Breakout Boot

Product Description

The 3M 7000145519 is a heat shrinkable cable breakout boot designed to insulate and seal cable breakouts in multiconductor armored or sheathed cables and conduit ends. Built from flame retardant, cross-linked polyolefin, this 2-way outlet boot meets material requirements of MIL-I-81765-1. An internal adhesive coating is factory-applied to provide reliable environmental sealing once the boot is shrunk in place. Licensed electricians and cable assembly technicians install this type of boot wherever split cable runs exit a common jacket or conduit end and require durable mechanical and electrical protection.

This boot is suited for use in industrial, commercial, and infrastructure wiring applications where multiconductor armored or sheathed cables must be protected at the point of breakout. Typical scenarios include panel wiring, cable tray terminations, and conduit end sealing in environments that demand flame retardant materials and environmental sealing performance. The 2-way outlet configuration accommodates a single cable splitting into two legs from a common entry.

Key Features

• Flame retardant, cross-linked polyolefin construction meets MIL-I-81765-1 material requirements
• Internal adhesive coating activates during heat shrink process for environmental sealing
• 2-way outlet design seals cable breakouts splitting into two conductors or legs
• Provides both electrical insulation and mechanical protection at cable exits
• Compatible with multiconductor armored cables, sheathed cables, and conduit ends

Compatibility

Designed for use with multiconductor armored or sheathed cables and conduit ends requiring breakout insulation and sealing at a 2-way split point.

Installation Notes

Installation is performed by licensed electricians or qualified cable assembly technicians. De-energize all circuits completely before working on cable terminations or breakout points. A heat gun capable of reaching the shrink temperature required for cross-linked polyolefin tubing is needed to activate the boot and internal adhesive. Follow applicable NEC guidelines for cable and conduit termination in the installation environment.
