3M 7100027861 Heat Shrink Thin-wall Tubing FP301 Blue

Product Description

The 3M 7100027861 is a thin-wall heat shrink tubing supplied in 48-inch lengths as a 12-piece pack. Based on the FP-301 series, this tubing provides a balanced combination of electrical insulation, physical durability, and chemical resistance suited to industrial and military-grade wiring applications. The blue color aids in circuit identification and organization. Licensed electricians and military MRO technicians routinely specify FP-301-series tubing for wire bundling, connector strain relief, and insulation repair on low-voltage and signal wiring assemblies.

This tubing is designed for use across a broad range of industrial and military applications where reliable electrical insulation and environmental protection are required. The 48-inch stick length gives technicians flexibility to cut pieces to fit specific connector backshells, wire splices, or terminal insulation tasks. The blue color coding is particularly useful in multi-conductor harness work where visual differentiation between circuits is a wiring-practice requirement.

Key Features

• FP-301 thin-wall construction balances electrical insulation with flexible physical properties
• Blue color supports circuit identification and color-coded wiring practices
• 48-inch stick length allows field cutting to application-specific sizes
• 12-piece pack quantity supports production and MRO stocking needs
• Suited for industrial and military wiring, connector insulation, and harness protection

Compatibility

Designed as an OEM-style heat shrink solution for industrial and military wiring harness assemblies requiring thin-wall tubing with standard FP-301 series electrical and chemical performance characteristics.

Installation Notes

Installation is performed by licensed electricians or trained wiring harness technicians. De-energize all circuits before applying heat shrink tubing to any conductor or connection. Use a calibrated heat gun to apply even heat along the length of the tubing — avoid open flame, which can cause uneven shrink and material damage. Follow applicable NEC guidelines and project-specific wiring specifications when selecting tubing diameter and color coding.
