3M 7100031028 Heat Shrink Cable Repair Sleeve 19.7in

Product Description

The 3M 7100031028 is a wraparound heat shrink cable repair sleeve engineered to restore damaged cable sheaths quickly and reliably. Once heat is applied, the inner wall — coated with a hot melt adhesive — forms a watertight, secure bond with the cable surface. A corrosion-proof metal closure clip locks the sleeve fully closed before shrinking, eliminating the need for additional fasteners. At 19.7 inches in length and weighing 2.15 pounds, it is built to deliver mechanical protection in aggressive environments. Licensed electricians and cable technicians are the primary installers for this type of repair product.

This sleeve is suited for repairing damaged cable sheaths on power and communication cables in residential, commercial, and industrial applications. It also serves as supplemental corrosion protection on undamaged cables and as an outer covering at cable joints. Its wraparound design allows installation without access to a free cable end, making it practical for mid-span repairs and junction points where conventional heat shrink tubing cannot be applied.

Key Features

• Wraparound construction allows installation at any point along the cable without requiring a free end
• Hot melt adhesive inner wall bonds to cable surface and creates a watertight seal when heat is applied
• Corrosion-proof metal closure clip secures the sleeve before and during heat application
• Provides mechanical protection against abrasion and stress in harsh or aggressive environments
• Suitable for cable sheath repair, cable joint covering, and supplemental corrosion protection

Compatibility

Designed as an OEM-style wraparound heat shrink sleeve for use with power and communication cable sheath repair applications where a watertight, mechanically protective covering is required.

Installation Notes

Installation is performed by a licensed electrician or qualified cable technician following applicable NEC guidelines. De-energize and lockout the circuit before beginning any cable repair work. Clean and dry the cable surface before positioning the sleeve to ensure proper adhesive bonding. Apply heat evenly with a calibrated heat gun, working from the center outward to avoid trapping air under the sleeve.
