3M 7100049966 Heat Shrink Tubing EPS300 1/2 in Black

Product Description

The 3M 7100049966 is a thin-wall heat shrink tubing designed for environmental protection and electrical insulation in a wide range of wiring and splicing applications. Sold as a pack of 10 individual pieces, each piece measures 6 inches in length with a nominal diameter of 1/2 inch. The EPS300 series uses a dual-wall or thin-wall construction that conforms tightly to conductors and connections when heat is applied, creating a durable barrier against moisture, abrasion, and contaminants. Electricians and low-voltage technicians regularly use this tubing to protect wire terminations, splices, and cable harness entry points.

This tubing is suited for residential and commercial electrical work, panel wiring, automotive harness repair, and instrumentation installations where a clean, insulated sleeve is required over a conductor or connector. The 6-inch cut length makes it practical for standard termination work without requiring field cutting on most common splice and lug applications. The black color provides UV resistance considerations and a clean finished appearance in exposed wiring runs.

Key Features

• Thin-wall construction provides environmental protection and electrical insulation after shrinking
• 6-inch pre-cut pieces reduce waste and speed up repetitive termination tasks
• 1/2-inch nominal diameter fits a broad range of conductor and connector sizes
• Black color finish suitable for exposed and semi-exposed wiring applications
• Pack quantity of 10 pieces supports job-site efficiency and organized inventory

Compatibility

Designed as an OEM-style heat shrink sleeve for use over wire splices, connectors, and cable terminations in electrical and low-voltage applications where a 1/2-inch nominal diameter thin-wall tubing is specified.

Installation Notes

Installation is performed by licensed electricians or qualified low-voltage technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any conductor or termination. Apply heat evenly using a heat gun set to an appropriate temperature range, working from the center of the sleeve outward to prevent air pockets. Do not use an open flame as a heat source, as uncontrolled heat can damage the tubing or adjacent insulation.
