3M 7000133556 Heat Shrink Thin-wall Tubing 3/8 in 48 in Black

Product Description

The 3M 7000133556 is a thin-wall heat shrink tubing in the FP-301 series, offered in a 3/8-inch diameter and 48-inch length in black. Designed for electrical insulation, bundling, and strain relief, this tubing conforms tightly to wire and connector profiles upon application of heat. The FP-301 formulation delivers a reliable balance of electrical, physical, and chemical resistance properties, making it suitable for demanding industrial and military-grade wiring environments. Licensed electricians, MRO technicians, and panel builders use this tubing during harness fabrication, terminal insulation, and field repair work.

This heat shrink tubing is used across a broad range of applications including industrial control panels, military and aerospace wiring assemblies, HVAC equipment wiring harnesses, and general electrical installations where reliable insulation and environmental protection are required. The black color aids in heat absorption during shrink and is a common standard in industrial wiring. The 48-inch length suits both bench work and in-field splicing tasks.

Key Features

• Thin-wall FP-301 construction provides consistent shrink performance and tight fit over conductors and terminals
• 48-inch length allows flexible cutting to job-specific requirements
• 3/8-inch recovered diameter suits a wide range of wire gauges and connector bodies
• Black color suitable for standard industrial and military wiring applications
• Balanced electrical, physical, and chemical resistance properties for demanding service environments

Compatibility

Designed as a general-purpose thin-wall heat shrink tubing suitable for use in industrial, military, HVAC, and electrical wiring applications requiring 3/8-inch diameter insulation coverage.

Installation Notes

Installation is performed by licensed electricians or trained wiring technicians. De-energize all circuits before applying heat shrink tubing to conductors or terminals. Use a calibrated heat gun to apply uniform heat — avoid open flame, which can cause uneven shrinkage or damage to the tubing. Follow applicable NEC guidelines for insulation and conductor protection in the relevant installation environment.
