3M 7010320999 FP301 Heat Shrink Tubing 1/2in 48in Blue

Product Description

The 3M 7010320999 is a thin-wall heat shrink tubing in the FP-301 series, supplied as a single 48-inch length in blue. It is designed to provide insulation, strain relief, and environmental protection on wire harnesses, splices, terminals, and cable bundles. FP-301 tubing delivers a reliable balance of electrical insulation, physical durability, and chemical resistance, making it appropriate for industrial wiring, panel builds, and mil-spec repair work. Licensed electricians, harness assemblers, and field technicians use this product as a standard step in termination and bundling workflows.

This tubing is suited for use in industrial control panels, electrical enclosures, automotive and aerospace harness assemblies, and military-grade wiring applications. The 1/2-inch nominal diameter accommodates a range of conductor and connector sizes common in low-voltage and signal wiring. The blue color supports color-coded circuit identification schemes used in multi-conductor assemblies and panel wiring.

Key Features

• Thin-wall FP-301 construction balances flexibility with electrical insulation performance
• 48-inch length per piece allows coverage of long runs or multiple shorter segments from a single piece
• 1/2-inch nominal diameter fits a wide range of wire gauges and connector bodies
• Blue color enables color-coded identification in multi-circuit assemblies
• Resistant to chemicals, moisture, and abrasion for use in demanding industrial environments
• Suitable for industrial and military wiring applications

Compatibility

Designed as an OEM-style heat shrink solution for industrial and military wiring harness, termination, and bundling applications requiring a 1/2-inch thin-wall tubing with standard shrink ratio.

Installation Notes

Heat shrink tubing is typically installed by electricians and harness technicians using a heat gun or similar controlled-heat tool. De-energize all circuits and verify zero voltage before applying tubing over live terminations. Apply heat evenly along the length of the tubing, working from the center outward to prevent air pockets or uneven shrinkage. Follow applicable NEC guidelines and manufacturer shrink-temperature specifications when selecting heat application tools.
