3M 7000057974 FP-301 1.5in White Heat Shrink Tubing 100ft

Product Description

The 3M 7000057974 is a thin-wall heat shrink tubing supplied on a 100-foot spool, designed for electrical insulation, bundling, and mechanical protection across industrial and military-grade applications. Based on the FP-301 series, this tubing delivers a reliable balance of electrical, physical, and chemical resistance properties. The white finish allows for easy labeling and identification in wiring assemblies. Licensed electricians and MRO technicians reach for FP-301 tubing when a clean, durable sleeve is needed on wire splices, terminals, and harness breakouts.

This tubing is suited for residential, commercial, and industrial wiring applications where a consistent, uniform wall thickness is required. It performs well in environments that demand resistance to moisture, mild chemicals, and abrasion. The 1.5-inch diameter makes it appropriate for medium-gauge wire bundles and connector backshells. Each spool contains 100 feet of continuous tubing, and the case quantity is 200 feet total across multiple spools.

Key Features

• Thin-wall construction for a low-profile sleeve with consistent shrink performance
• White color supports marker and label adhesion for circuit identification
• 100-foot continuous spool minimizes waste on longer harness runs
• Balanced electrical and chemical resistance properties suitable for industrial and military applications
• FP-301 series formulation provides reliable mechanical protection at wire terminations and splices

Compatibility

Designed as an OEM-style replacement and general-use heat shrink sleeve compatible with standard 1.5-inch diameter wire bundles, terminals, and connector applications across industrial and military wiring assemblies.

Installation Notes

Heat shrink tubing is typically installed by electricians and wiring harness technicians using a calibrated heat gun applied evenly along the length of the sleeve. Always de-energize and lock out the circuit before sleeving any termination or splice. Avoid open-flame heat sources, which can scorch the tubing and compromise its electrical properties. Work in accordance with applicable NEC guidelines for insulation and wire protection requirements.
