3M 7100025161 FP-301 Heat Shrink Tubing 1/2 in Red 200 Ft

Product Description

The 3M 7100025161 is a thin-wall heat shrink tubing from the FP-301 product line, supplied on a 200-foot bulk spool in red. FP-301 tubing is a general-purpose polyolefin heat shrink material engineered to provide a reliable balance of electrical insulation, physical durability, and chemical resistance. It is used to insulate, bundle, protect, and identify wire and cable assemblies across industrial and military applications. Licensed electricians and experienced wiring technicians are the primary installers. The tubing ships in a continuous spool format suited for high-volume wire harness shops and field service operations requiring consistent, cut-to-length flexibility.

This tubing is well suited for wire insulation, cable bundling, strain relief, and color-coded identification in both industrial control panels and military-grade wiring applications. The red color supports color-coded circuit identification schemes. The 1/2-inch nominal size accommodates a range of conductor and connector configurations commonly encountered in panel wiring and harness fabrication. Bulk spool packaging makes it practical for production environments where large quantities are consumed regularly.

Key Features

• Thin-wall polyolefin construction provides electrical insulation and chemical resistance
• Red color enables color-coded wire and circuit identification
• 200-foot bulk spool format reduces waste and supports high-volume applications
• 1/2-inch nominal diameter fits a broad range of conductors and connectors
• Suitable for industrial and military wiring applications

Compatibility

Designed as a general-purpose heat shrink tubing solution for industrial control wiring, military cable assemblies, and commercial wire harness fabrication where a 1/2-inch thin-wall shrink tube is required.

Installation Notes

Heat shrink tubing of this type is installed by electricians and wire harness technicians following applicable NEC guidelines for insulation and wire protection. Cut tubing to the required length before positioning over the conductor or connection point. Apply uniform heat using a heat gun, avoiding open flame, to achieve consistent shrinkage without scorching. Always power down and de-energize circuits completely before applying heat shrink to live wiring assemblies.
