3M 7010400841 Heat Shrink Tubing FP301 3/8 in 48 in Blue

Product Description

The 3M 7010400841 is a thin-wall heat shrink tubing in the FP-301 series, designed to provide reliable electrical insulation, strain relief, and environmental protection for wire and cable terminations. Sized at 3/8 inch supplied diameter and 48 inches in length, this blue tubing is suited for color-coded wire management and identification in industrial and military-grade wiring assemblies. FP-301 thin-wall construction allows fast shrink times and a clean, low-profile finish over conductors, connectors, and splices. Licensed electricians, panel builders, and MRO technicians are the primary installers.

This tubing is applied across a broad range of industrial and military wiring applications where a dependable balance of electrical insulation, physical durability, and chemical resistance is required. The blue color makes it a practical choice for phase identification, circuit coding, or harness organization in panel wiring, control cabinets, and field repair work. It is sold per piece at 48 inches per length.

Key Features

• Thin-wall FP-301 series construction for low-profile insulation and fast shrink response
• 3/8 inch supplied diameter accommodates a range of wire gauges and small connector bodies
• 48-inch length provides flexibility for full-run coverage or cut-to-length field use
• Blue color supports color-coded wiring and circuit identification standards
• Balanced electrical, physical, and chemical properties suitable for industrial and military applications

Compatibility

Designed as an OEM-style heat shrink solution for industrial and military wiring assemblies requiring thin-wall polyolefin tubing at the 3/8 inch size.

Installation Notes

Installation is performed by licensed electricians or qualified wiring technicians. De-energize all circuits before applying heat shrink tubing to any live termination or splice. A heat gun set to the appropriate temperature range for polyolefin tubing should be used for even shrink; open flame tools are not recommended. Follow applicable NEC guidelines for insulation and wire protection requirements in the installation environment.
