3M 7100030655 Heat Shrink Tubing 3/8 in Black 100 Ft

Product Description

The 3M 7100030655 is a thin-wall heat shrink tubing supplied on a 100-foot spool in black. Rated for electrical insulation, strain relief, and bundling applications, this FP-301 series tubing shrinks when heat is applied, conforming tightly around wire terminations, splices, and conductors. The 3/8-inch nominal diameter makes it suited for mid-range wire gauges and connector bodies commonly found in industrial, automotive, and electrical panel wiring. Electricians and maintenance technicians apply this tubing using a heat gun to achieve a clean, insulated finish on exposed conductors and connections.

This tubing is used in residential and commercial electrical work, control panel assembly, OEM wiring harnesses, and field service repairs. The 100-foot spool format supports production runs and high-volume service work where individual pre-cut pieces would be inefficient. Typical applications include insulating butt splices, covering terminal ends, and bundling wire groups in enclosures and raceways.

Key Features

• Thin-wall FP-301 construction allows fast, uniform shrink with standard heat gun equipment
• 3/8-inch nominal diameter fits mid-range conductor and connector sizes
• Black color provides UV resistance and blends with standard wiring conventions
• 100-foot spool format reduces waste and suits continuous production or service use
• Flexible after shrinking for installations with vibration or movement

Compatibility

Designed as a general-purpose thin-wall heat shrink tubing for use in electrical, electronic, and light industrial wiring applications requiring insulation and mechanical protection on conductors and splice points.

Installation Notes

Installation is typically performed by licensed electricians or experienced technicians working with low-voltage and line-voltage wiring. De-energize all circuits completely before applying heat shrink tubing to any conductor or termination. Apply heat evenly using a heat gun, working from the center of the tubing outward to prevent air pockets or uneven shrink. Follow applicable NEC requirements for insulation ratings and conductor protection in the installation environment.
