3M 7100025158 FP-301 Heat Shrink Tubing 1/16 in Clear 1000 Ft

Product Description

The 3M 7100025158 is a thin-wall heat shrink tubing sold in a 1000-foot bulk spool, designed for electrical insulation, bundling, and strain relief across industrial and military-grade applications. The FP-301 series delivers a reliable balance of electrical, physical, and chemical resistance properties. At a nominal diameter of 1/16 inch, this tubing suits small-gauge wire terminations and connector backshells where a low-profile, clean shrink is required. It ships in a continuous spool format, making it practical for high-volume production environments and field service kits alike. Electrical contractors, MRO shops, and military/defense assembly technicians are the primary installers.

This tubing is suited for residential, commercial, and industrial electrical work where consistent insulation and moisture resistance are needed on small conductors. The clear (CR) finish allows visual inspection of the underlying wire or splice after installation without removing the tubing. Bulk spool format reduces per-foot cost in production runs and supports high-throughput wire harness assembly operations. The FP-301 designation indicates a standard 2:1 shrink ratio product within the 3M heat shrink line.

Key Features

• 1/16 inch nominal diameter suits small-gauge wire and tight connector backshell applications
• Thin-wall construction for low-profile installations with minimal added bulk
• Clear finish allows post-shrink visual inspection of conductors and splices
• 1000-foot bulk spool reduces per-foot cost in high-volume or production environments
• Engineered for both industrial and military application requirements
• Balanced electrical, physical, and chemical resistance properties across the FP-301 series

Compatibility

Designed as an OEM-style replacement and general-use heat shrink tubing compatible with standard small-gauge wire insulation applications requiring a thin-wall, 2:1 shrink-ratio sleeve in the 1/16 inch size range.

Installation Notes

Installation is performed by licensed electricians or trained wire harness technicians following applicable NEC guidelines. De-energize all circuits completely before applying heat shrink tubing to any conductor or termination. Use a calibrated heat gun set to the appropriate temperature range for the FP-301 material — avoid open flame, which can cause uneven shrink or damage the tubing. Work from one end of the tubing to the other to prevent air pockets from forming beneath the sleeve.
