3M 7000133605 Heat Shrink Thin-wall Tubing FP301

Product Description

The 3M 7000133605 is a thin-wall heat shrink tubing in the FP-301 series, designed to provide reliable insulation, strain relief, and environmental protection for wire and cable assemblies. Rated for a broad range of industrial and military-grade applications, FP-301 tubing delivers a consistent balance of electrical insulation, mechanical strength, and chemical resistance in a single-wall, flexible sleeve. Electricians, industrial maintenance techs, and military-spec assembly technicians install this tubing to protect exposed conductors, terminals, splices, and connectors from moisture, abrasion, and contamination. The 48-inch length and 3-inch nominal diameter make it well suited for large-gauge wire bundling and cable harness work.

FP-301 thin-wall heat shrink tubing is used across electrical and electronic assembly environments where consistent shrink performance and long-term insulation integrity are required. Common applications include wire harnessing in industrial control panels, military and aerospace wiring assemblies, HVAC equipment wiring, and general commercial electrical installations. The tubing applies standard 2:1 shrink ratio performance, conforming tightly to irregular surface profiles and connector geometries when heated.

Key Features

• Thin-wall construction provides flexible, low-profile coverage for wire and cable assemblies
• Balanced electrical, physical, and chemical properties suited for industrial and military applications
• 48-inch length accommodates long wire runs and large-diameter bundling tasks
• 3-inch nominal diameter fits large-gauge conductors and multi-wire harnesses
• Resists moisture, abrasion, and common industrial chemicals after shrink

Compatibility

Designed as an OEM-style heat shrink sleeve for use on wire and cable assemblies requiring thin-wall insulation and strain relief across industrial and military-grade electrical applications.

Installation Notes

Installation is performed by qualified electricians or wire harness technicians following applicable NEC guidelines. De-energize all circuits completely before applying heat shrink tubing to any conductor or terminal. Use a calibrated heat gun with a suitable nozzle to apply uniform heat; avoid open-flame heat sources, which can cause uneven shrinkage or damage to the tubing. Slide tubing fully over the work area before applying heat, as repositioning is not possible once shrink begins.
