3M 7000005975 FP-301 Heat Shrink Tubing 1.5 in Black 100 Ft

Product Description

The 3M 7000005975 is a thin-wall heat shrink tubing sold on a bulk spool, designed for protecting and insulating wire splices, terminals, and cable bundles in electrical and industrial applications. Part of the FP-301 series, this tubing delivers a reliable balance of electrical insulation, physical protection, and chemical resistance. At 1.5 inches in nominal diameter and 100 feet per spool, it suits high-volume wiring jobs where consistent, professional-grade sleeving is required. Licensed electricians, industrial maintenance technicians, and military-spec wiring crews are the primary installers of this product type.

FP-301 thin-wall heat shrink tubing is used across a broad range of industrial and military wiring applications. It performs well in environments that demand reliable insulation integrity under mechanical stress or exposure to common shop chemicals. The bulk 100-foot spool format makes it practical for panel shops, wire harness fabrication, and service vehicles stocking a range of repair materials. It is suitable for both indoor and outdoor electrical assemblies where a clean, shrunk-fit sleeve is needed over conductors, connectors, or solder joints.

Key Features

• Thin-wall FP-301 construction balances flexibility with durable electrical insulation
• 1.5 inch nominal diameter accommodates larger conductors, cable bundles, and connectors
• Black color provides UV-resistant identification and a professional finish
• 100-foot bulk spool reduces per-foot cost on high-volume wiring projects
• Suitable for industrial and military-specification wiring applications
• Chemical-resistant material stands up to common solvents and shop fluids

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve for electrical wire, cable bundles, terminals, and connector backshells where a 1.5 inch nominal diameter shrink tube is specified.

Installation Notes

Installation is typically performed by licensed electricians or qualified wiring technicians. De-energize all circuits completely before applying heat shrink sleeving to any conductor or assembly. Use a calibrated heat gun to apply even, controlled heat along the length of the tubing — open flame torches are not recommended for thin-wall tubing as they risk burning or uneven shrinkage. Follow applicable NEC guidelines and any project-specific wiring specifications when selecting shrink ratio and wall thickness for the application.
