3M 7000138426 Heat Shrink Cable Repair Sleeve 29.5in

Product Description

The 3M 7000138426 is a wraparound heat shrink cable repair sleeve engineered to restore damaged cable sheaths quickly and reliably. The sleeve wraps around the cable without requiring end access, making it practical for in-place field repairs. Its inner wall is coated with hot melt adhesive that activates under heat to form a watertight, corrosion-resistant bond along the entire contact surface. A corrosion-proof metal clip secures the sleeve edges fully before shrinking begins. At 29.5 inches in length, this sleeve covers substantial repair or protection spans on medium and large-diameter cables in demanding environments.

This sleeve is suited for repairing damaged cable sheaths on power, control, and communications cables in industrial, utility, and infrastructure applications. It also serves as supplemental corrosion protection on undamaged cables and as an outer wrap over cable joints. Electrical contractors, utility crews, and cable splicing technicians typically install this product in underground, direct-buried, aerial, and exposed conduit runs where mechanical durability and moisture exclusion are critical.

Key Features

• Wraparound design allows installation without end access to the cable
• Hot melt adhesive inner wall creates a watertight seal when heat is applied
• Corrosion-proof metal closure clip fully secures the sleeve seam before shrinking
• Suitable for cable sheath repair, joint protection, and corrosion protection on undamaged cables
• Rated for aggressive environments with high mechanical stress resistance
• 29.5-inch length accommodates extended repair and protection zones

Compatibility

Designed as an OEM-style wraparound repair solution for medium and large-diameter power, control, and communications cable sheaths where heat shrink installation is specified.

Installation Notes

Installation is performed by qualified electricians or cable splicing technicians following applicable NEC and site-specific safety requirements. De-energize and lock out the affected circuit before beginning any cable repair work. Wrap the sleeve around the repair zone, secure the metal closure clip, then apply heat evenly with a propane torch or heat gun working from the center outward to avoid trapping air. Allow the sleeve to cool fully before returning the cable to service.
