3M 7000132578 Heat Shrinkable Cable Breakout Boot

Product Description

The 3M 7000132578 is a heat shrinkable cable breakout boot designed for dependable insulating and sealing of cable breakouts in multiconductor armored or sheathed cables and conduit ends. Manufactured under the HDBB series, this boot is constructed from flame retardant, cross-linked polyolefin and meets the material requirements of MIL-I-81765-1. It features an internal adhesive lining that activates during heat shrink installation, creating a reliable environmental seal. The three-way outlet configuration accommodates a single cable entry splitting into three conductors, making it well suited for cable terminations that require both mechanical protection and moisture exclusion.

This boot is intended for use in electrical installations involving multiconductor armored or sheathed cables and conduit terminations. It is supplied in black and is sold individually. Licensed electricians and low-voltage wiring technicians typically install this component in commercial, industrial, and infrastructure wiring systems where environmental sealing at cable breakout points is required by specification or code. The three-way outlet design is a common configuration in panel feeds and branch circuit terminations within conduit assemblies.

Key Features

• Flame retardant, cross-linked polyolefin construction meets MIL-I-81765-1 material requirements
• Internal adhesive coating provides environmental sealing during heat shrink activation
• Three-way outlet configuration for single-entry, three-conductor breakout applications
• Compatible with multiconductor armored cables, sheathed cables, and conduit ends
• Provides both electrical insulation and mechanical protection at cable breakout points
• Black color finish; sold individually (quantity of 1 per unit)

Compatibility

Designed as an OEM-style replacement and standard fitment for heat shrinkable breakout boot applications on multiconductor armored or sheathed cables and conduit ends requiring a three-way outlet configuration.

Installation Notes

Installation is performed by licensed electricians following applicable NEC requirements for cable termination and insulation. De-energize and lock out the circuit before beginning any termination work. Apply heat evenly using an appropriate heat gun, starting from the center of the boot and working outward to activate the internal adhesive and achieve a uniform seal. Avoid using open flame tools, as uneven or excessive heat can damage the boot or compromise the seal.
