3M 7000138423 Heat Shrink Cable Repair Sleeve 47.2 in

Product Description

The 3M 7000138423 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 access to the cable ends, making it practical for in-place repairs on installed wiring. An inner wall coated with hot-melt adhesive creates a watertight, corrosion-resistant bond when heat is applied. A corrosion-proof metal clip secures the sleeve fully closed before shrinking. At 47.2 inches in length, this sleeve suits longer repair spans and is well-suited for licensed electricians and cable installation crews working in demanding environments.

This sleeve is appropriate for repairing mechanically damaged cable outer sheaths on power distribution, telecommunications, and instrumentation cables. It also serves as supplemental corrosion protection on undamaged cables and as an outer covering over cable joints. The wraparound format allows installation without disturbing terminations or pulling cable back through conduit, reducing downtime during repair work. It performs reliably in aggressive environments including direct burial, wet locations, and areas with significant mechanical stress.

Key Features

• Wraparound design installs without access to cable ends
• Hot-melt adhesive inner wall bonds to cable sheath for a watertight seal
• Corrosion-proof metal clip fully closes the sleeve before heat application
• Suitable for cable sheath repair, joint covering, and added corrosion protection on undamaged cables
• Rated for use in mechanically aggressive and corrosive environments
• 47.2 inch length accommodates longer repair zones

Compatibility

Designed as an OEM-style replacement and repair solution for cable sheath damage on power, telecommunications, and instrumentation cables where wraparound access is required.

Installation Notes

Installation is typically performed by a licensed electrician or qualified cable technician. De-energize and lock out the affected circuit before beginning any cable repair work in accordance with applicable NFPA 70 (NEC) lockout-tagout requirements. Clean and dry the cable surface before positioning the sleeve. Apply heat evenly with a propane torch or hot-air gun, working from the center outward, until adhesive flows from the sleeve edges confirming a complete seal.
