3M 7010348206 Heat Shrink Heavy-wall Cable Sleeve 12 in

Product Description

The 3M 7010348206 is a heavy-wall, heat-shrinkable cable sleeve designed for electrical splices, connections, and terminations in demanding installation environments. Built from cross-linked polyolefin with a factory-applied internal adhesive and sealant, this sleeve delivers both mechanical protection and environmental sealing when shrunk in place. The 12-inch cut-to-length format allows technicians to size the sleeve to the application without waste. Rated to 1 kV and UL Listed 486D for 600V (File Number E102356), the sleeve meets certification requirements for professional electrical work across a range of service conditions.

This cable sleeve is suited for use in residential, commercial, and industrial electrical applications where insulated splices and terminations require durable environmental protection. Electricians and electrical contractors use sleeves of this type when terminating or splicing conductors in conduit, junction boxes, and exposed runs. The 12-inch length accommodates a variety of conductor sizes and splice configurations. The cross-linked polyolefin construction resists splitting under heat application, and the fast-shrink characteristics support efficient installation pacing on the job.

Key Features

• Cross-linked polyolefin construction is highly split resistant for reliable shrink performance
• Factory-applied internal adhesive and sealant provides environmental and moisture protection at the splice
• Rated to 1 kV with UL Listed 486D certification for 600V service (File Number E102356)
• CSA rated for additional certification coverage
• Fast-shrinking material supports rapid installation on active job sites
• Cut-to-length 12-inch format reduces material waste

Compatibility

Designed as an OEM-style replacement or direct-use sleeve for electrical splice, connection, and termination applications requiring heavy-wall heat-shrink protection rated to 1 kV.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before preparing any splice or termination. Apply heat evenly along the sleeve using an appropriate heat gun, working from the center outward to allow the adhesive sealant to flow uniformly. Avoid open-flame heat sources, which can cause uneven shrink or damage the sleeve material.
