3M 7010400863 Heat Shrink Tubing FP301 1/4 in 48 in Blue

Product Description

The 3M 7010400863 is a thin-wall heat shrink tubing sold as a single 48-inch length in blue. Based on the FP-301 series, this tubing delivers a balanced combination of electrical insulation, physical durability, and chemical resistance. It is designed for wire bundling, splicing insulation, strain relief, and environmental protection of conductors and terminals. Licensed electricians, industrial maintenance technicians, and military MRO professionals commonly install this tubing using a heat gun or oven during harness assembly or field repair work.

FP-301 thin-wall heat shrink tubing is suited for a wide range of industrial and military wiring applications where a reliable, low-profile insulating sleeve is required. The blue color aids in color-coded circuit identification on multi-conductor harnesses. At 1/4-inch nominal diameter and 48 inches in length, this piece is a practical cut length for bench work or field splicing on standard wire gauges that fall within the tubing recovery range.

Key Features

• Thin-wall FP-301 construction balances electrical insulation with flexible, low-profile coverage
• Blue coloring supports color-coded wire and harness identification
• 48-inch length provides a ready-to-cut piece for bench or field use
• 1/4-inch nominal diameter suits a range of standard conductor sizes
• Chemical resistance protects against common industrial fluids and contaminants
• Suitable for both industrial and military wiring specifications

Compatibility

Designed as an OEM-style replacement or supply-grade component for industrial and military wiring harness assemblies requiring thin-wall heat shrink sleeving at 1/4-inch nominal diameter.

Installation Notes

Installation is performed by electricians or harness technicians using a calibrated heat gun or convection oven. Ensure the wire or terminal is fully seated and the tubing is centered over the joint before applying heat. Apply heat evenly along the length of the tubing to achieve uniform shrinkage and avoid scorching. Follow applicable NEC guidelines and any relevant military or industrial wiring standards for harness assembly.
