3M 7100025157 FP-301 Heat Shrink Tubing 1 in Yellow

Product Description

The 3M 7100025157 is a thin-wall heat shrink tubing sold on a bulk spool, designed to provide durable insulation and protection for wire harnesses, splices, terminals, and electrical connections. Based on the FP-301 series, this tubing delivers a dependable balance of electrical insulation, physical flexibility, and chemical resistance suitable for demanding industrial and military-grade wiring applications. It is yellow in color, sized at 1 inch, and supplied in a 100-foot bulk spool format. Electricians, military contractors, and industrial maintenance technicians commonly specify this tubing for high-volume or multi-connection jobs where consistent, reliable heat shrink coverage is required.

This tubing is suited for use in industrial control panels, military wiring assemblies, and commercial electrical installations where environmental and mechanical protection of conductors is needed. The bulk spool format makes it practical for shop use or job sites requiring repeated application across many connections. Its thin-wall construction allows for efficient shrink times and a low-profile finished result on insulated conductors and bundled wire assemblies.

Key Features

• Thin-wall construction for fast, uniform shrinkage and low-profile finished coverage
• Yellow color aids in color-coded wiring identification and organization
• Bulk 100-foot spool format supports high-volume shop or field use
• Balanced electrical, physical, and chemical resistance properties per FP-301 series specification
• Suitable for industrial and military wiring applications

Compatibility

Designed as an OEM-style heat shrink solution for insulating and protecting electrical splices, terminals, and conductor bundles in industrial and military wiring assemblies where 1-inch thin-wall tubing is specified.

Installation Notes

Installation is performed by licensed electricians or trained wiring technicians following applicable NEC guidelines. De-energize all circuits completely before applying heat shrink tubing to any connection or splice. Use a calibrated heat gun at the appropriate temperature range for the FP-301 series to achieve full shrink without damaging adjacent insulation or components. Do not use an open flame as a heat source, as this can cause uneven shrink or damage to the tubing.
