3M 7010400825 Heat Shrink Tubing FP301 1/2 in 48 in Red

Product Description

The 3M 7010400825 is a thin-wall heat shrink tubing in the FP-301 series, sized at 1/2 inch diameter and 48 inches in length in red. FP-301 tubing is a polyolefin-based product that shrinks when heat is applied, creating a tight, protective sleeve over wire splices, terminals, and cable bundles. It is widely used in industrial wiring and electrical assembly applications where reliable insulation and physical protection are required. Licensed electricians, industrial maintenance technicians, and military/aerospace contractors regularly specify FP-301 tubing for its consistent shrink performance and dielectric properties.

This tubing is suited for residential, commercial, and industrial electrical work where conductors and connections need insulation, strain relief, or environmental protection. The red color aids in circuit identification and phase coding. At 48 inches per piece, it can be cut to length on the job to suit a range of conductor sizes and splice configurations. It performs well in panel wiring, harness assembly, and field repair scenarios.

Key Features

• Thin-wall polyolefin construction provides a balance of electrical, physical, and chemical resistance
• 1/2 inch nominal diameter fits a range of conductor and bundle sizes
• 48 inch length allows on-site cutting to required lengths
• Red color supports color-coded circuit identification
• Suitable for industrial and military-grade wiring applications

Compatibility

Designed as an OEM-style replacement and standard-use heat shrink sleeve for electrical wiring assemblies requiring 1/2 inch thin-wall tubing in industrial and military applications.

Installation Notes

Installation is performed by licensed electricians or qualified technicians. De-energize all circuits before applying heat shrink tubing to any conductor or terminal. Use a heat gun set to the appropriate temperature range for polyolefin tubing — do not use an open flame, as this can cause uneven shrinkage or material damage. Work practices should comply with applicable NEC requirements for insulation and wiring methods.
