3M 7100086432 Heat Shrink Heavy Wall Cable Sleeve

Product Description

The 3M 7100086432 is a heavy-wall heat shrink cable sleeve designed for electrical cable terminations and splices requiring a durable, moisture-resistant seal. Constructed from cross-linked polyolefin with a factory-applied internal adhesive and sealant, this sleeve provides a tight, split-resistant fit when heat is applied. Rated to 1 kV and UL Listed 486D for 600V (File Number E102356) with a CSA rating, it meets common electrical code requirements for insulated connections. Electricians and field technicians install these sleeves where environmental sealing and mechanical protection are priorities.

This sleeve is sold in bulk cut-to-length format, making it well suited for high-volume service work, panel shops, and electrical contractors who need flexible sleeve lengths across a range of conductor sizes. The fast-shrink characteristic of the cross-linked polyolefin material reduces installation time on multi-cable runs. The factory-applied adhesive flows during shrinking to seal the sleeve ends against moisture ingress, dust, and contaminants, making it appropriate for both indoor and outdoor electrical applications.

Key Features

• Cross-linked polyolefin construction provides high split resistance and dimensional stability after shrinking
• Factory-applied internal adhesive and sealant bonds to the cable jacket and seals sleeve ends during installation
• Rated to 1 kV; UL Listed 486D for 600V (File Number E102356) with CSA rating
• Fast-shrink design reduces time on multi-cable termination and splice work
• Cut-to-length bulk format allows custom sleeve lengths without waste

Compatibility

Designed as an OEM-style heavy-wall heat shrink sleeve for use on low-voltage electrical cables and wire bundles requiring insulation, mechanical protection, and environmental sealing at terminations and splices.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements for insulated splices and terminations. De-energize all circuits completely before applying the sleeve over the conductor or splice. Apply uniform heat with a heat gun working from the center of the sleeve outward toward the ends to allow the adhesive to flow and seat evenly. Avoid open-flame heat sources, which can damage the sleeve material and compromise the sealant.
