3M 7100082992 Heat Shrink Sleeve 3/8 in Id 6 in Black

Product Description

The 3M 7100082992 is a polyolefin heat shrink sleeve designed for insulating, bundling, and protecting electrical wire connections. It features a 3:1 shrink ratio, starting at 3/8 inch inner diameter and shrinking down to 0.12 inches after application. At 6 inches in overall length, it provides reliable coverage across a range of wire terminations and splices. The sleeve activates at 249.8 degrees F and is rated for continuous operation from -67 to 230 degrees F. It is sold in packages of 10 and is compatible with wire gauges from 16 AWG to 6 AWG. Black coloring aids in identification and provides a clean finished appearance on completed work.

This sleeve is used in residential and commercial electrical installations wherever insulated wire protection, strain relief, or moisture sealing is required. It is suited for panel wiring, junction box terminations, and field splices where a compact, durable sleeve is needed. Licensed electricians and service technicians install this type of product during new construction, panel upgrades, and equipment service calls. Its resistance to corrosion, fluids, fungus, and water makes it appropriate for installations in wet or harsh environments.

Compatibility

Designed for use with wire gauges from 16 AWG to 6 AWG. Suitable as a general-purpose heat shrink sleeve for electrical wire insulation and termination protection in both residential and commercial applications.

Installation Notes

Installation is performed by a licensed electrician or qualified technician. De-energize all circuits before applying heat shrink sleeving to any wire or termination. Use a calibrated heat gun to apply even heat around the sleeve until full shrinkage is achieved — avoid open flame tools that can scorch the material or damage adjacent wiring. Follow applicable NEC requirements for wire insulation and termination methods in the jurisdiction of installation.
