3M 7000138428 Heat Shrink Cable Repair Sleeve 47.2in

Product Description

The 3M 7000138428 is a wraparound heat shrink cable repair sleeve engineered to restore and protect damaged cable sheaths in electrical and utility applications. The sleeve wraps around the cable without requiring access to the cable end, making it practical for in-place repairs. The inner wall is coated with hot melt adhesive that activates when heat is applied, forming a watertight, corrosion-resistant bond with the cable surface. A corrosion-proof metal clip secures the sleeve closure before and during shrinkage. At 47.2 inches in length, this sleeve suits repairs on longer cable runs or larger joint protection zones.

This sleeve is suited for repairing mechanical damage to cable sheaths, protecting cable joints, and adding supplemental corrosion protection to undamaged cable sections. It performs in aggressive environments including direct burial, underground conduit, and industrial settings where moisture, chemicals, or mechanical stress are present. Licensed electricians and utility cable technicians are the typical installers, though the tool requirements are minimal and the application process is straightforward for any qualified trade professional working with medium or low-voltage power cable.

Key Features

• Wraparound design allows installation without access to cable end
• Hot melt adhesive inner wall creates a watertight seal when heat is applied
• Corrosion-proof metal clip fully closes and holds the sleeve during installation
• Suitable for cable sheath repair, joint protection, and additional corrosion protection on intact cables
• 47.2 inch length accommodates extended repair zones and cable joint applications

Compatibility

Designed as an OEM-style replacement and repair solution for damaged cable sheaths and cable joints on low- and medium-voltage power cables where a wraparound heat shrink sleeve is specified.

Installation Notes

De-energize and lock out the affected circuit before beginning any cable repair work in accordance with NFPA 70E electrical safety procedures. Clean and dry the cable surface in the repair area before positioning the sleeve. Apply heat evenly using a propane torch or heat gun, working from the center outward to activate the adhesive and achieve full shrinkage. Verify the metal clip is fully seated and the sleeve edges show adhesive flow at both ends before returning the circuit to service.
