3M 7000132157 Heat Shrink Heavy-wall Cable Sleeve

Product Description

The 3M 7000132157 is a heavy-wall heat shrink cable sleeve rated for 1 kV service, designed to provide insulation, environmental sealing, and mechanical protection on cable terminations and splices. The sleeve ships in an expanded inner diameter of 1.10 inches and recovers to 0.37 inches upon application of heat, producing a firm, adhesive-lined seal around conductors ranging from 2 AWG through 4/0 AWG. Each sleeve measures 9 inches in length. Licensed electricians and cable termination technicians install this product during medium-duty low-voltage cable preparation and end-sealing work.

This heavy-wall sleeve is suited for residential and light commercial electrical installations where cable ends require durable insulation and moisture protection. The 1 kV rating covers standard low-voltage wiring applications. It is appropriate for use on copper or aluminum conductors in the 2 AWG to 4/0 AWG range. The product is sold individually, with a minimum order quantity of 100 pieces per case, making it practical for contractors stocking supplies for multiple cable termination jobs.

Key Features

• Heavy-wall construction provides mechanical protection and insulation at cable terminations
• Rated for 1 kV service, compatible with ITCSN-1100-9-Bulk series
• Expanded inner diameter of 1.10 inches recovers to 0.37 inches for a tight, sealed fit
• 9-inch length accommodates standard termination and splice overlap requirements
• Covers 2 AWG through 4/0 AWG conductor sizes
• Adhesive lining creates an environmental seal against moisture and contaminants

Compatibility

Specified for use with 1 kV ITCSN-1100-9-Bulk applications and compatible with 2 AWG through 4/0 AWG conductors.

Installation Notes

Installation is performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the circuit before beginning any cable termination work. Apply heat evenly along the sleeve using a heat gun, working from the center outward to avoid trapping air and to ensure uniform recovery. Do not use an open flame as a heat source, as uneven heat can prevent full recovery and compromise the seal.
