3M 7100111119 Heat Shrink Tubing 1/8 in 48 in Black

Product Description

The 3M 7100111119 is a thin-wall heat shrink tubing from the FP-301 series, offered in a 1/8-inch diameter and 48-inch length in black. Heat shrink tubing of this type provides electrical insulation, mechanical protection, and strain relief for wire terminations, splices, and bundled conductors. Once applied with a heat gun, the tubing shrinks uniformly around the substrate to form a snug, protective sleeve. The FP-301 series is a polyolefin-based product known for its balance of electrical, physical, and chemical resistance properties, making it suitable for both industrial and military-grade wiring applications.

This tubing is used in a wide range of installation environments where reliable insulation and protection of conductors is required. Common applications include panel wiring, harness fabrication, military and aerospace wire assemblies, marine wiring, and general electrical maintenance. The black color is standard for wire identification and UV-light environments. Electricians, harness builders, and MRO technicians regularly use FP-301 series tubing for both new installation and field repair work.

Key Features

• Thin-wall polyolefin construction provides a balance of electrical insulation and chemical resistance
• 1/8-inch nominal diameter suits small-gauge wire terminations and conductor bundles
• 48-inch length allows cutting to custom lengths on the job
• Black finish suitable for general wiring, UV-exposed environments, and color-coded harness work
• Rated for industrial and military wiring applications

Compatibility

Designed as an OEM-style thin-wall heat shrink sleeve for use with small-gauge conductors and wire terminations in industrial and military wiring assemblies.

Installation Notes

Installation is performed by electricians, harness technicians, and qualified maintenance personnel. De-energize all circuits before applying heat shrink tubing to live conductors or terminal connections. Apply heat evenly using a calibrated heat gun, working from one end of the tubing toward the other to prevent air pockets or uneven shrinkage. Follow applicable NEC guidelines and project specifications for insulation type and minimum wall thickness requirements.
