3M 7000133566 Heat Shrink Tubing FP301 3/4 in 48 in White

Product Description

The 3M 7000133566 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable insulation and mechanical protection for wire splices, terminations, and bundled conductors. It ships in a 48-inch length with a 3/4-inch recovered diameter and a white finish for easy identification in finished wiring assemblies. The FP-301 formulation delivers a balanced combination of electrical insulation properties, physical toughness, and resistance to common industrial chemicals. Licensed electricians and electronics technicians use this tubing across a wide range of production, maintenance, and repair applications.

This tubing is suited for both industrial and military-specification wiring applications where consistent shrink performance and long-term insulation integrity are required. The white color makes it appropriate for finished wire harnesses, panel wiring, and applications where labeling or visual inspection is a priority. It performs in demanding environments where exposure to fluids, abrasion, or temperature variation is a regular factor on the job.

Key Features

• Thin-wall FP-301 construction balances electrical insulation with flexible, low-profile coverage
• 3/4-inch diameter accommodates a range of wire gauges and small conductor bundles
• 48-inch length allows field cutting to custom sizes without waste
• White finish supports visual organization and post-installation marking
• Suitable for industrial and military wiring applications requiring reliable shrink performance

Compatibility

Designed as an OEM-style replacement and general-use heat shrink solution for industrial and military electrical wiring, harness construction, and termination protection applications.

Installation Notes

Installation is typically performed by licensed electricians or qualified wiring technicians. De-energize all circuits before applying heat shrink tubing to any conductor or termination. Use a heat gun calibrated for shrink tubing work and apply heat evenly along the length of the tubing to avoid uneven shrinkage or scorching. Follow applicable NEC requirements for insulation ratings and conductor protection in the installation environment.
