3M 7000133543 FP301 Heat Shrink Tubing 1/8 in 48 in Black 25pc

Product Description

The 3M 7000133543 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable electrical insulation, mechanical protection, and resistance to common industrial chemicals. Measuring 1/8 inch in diameter and 48 inches in length, each black piece installs quickly over wire terminations, splices, and connector backshells. The FP-301 formulation delivers a balanced combination of dielectric, physical, and chemical properties suited to demanding environments. Electricians, industrial maintenance technicians, and military MRO professionals install this tubing wherever a clean, low-profile insulating sleeve is required.

This tubing is appropriate for use in industrial control panels, wire harness assemblies, and field wiring applications where thin-wall shrink protection is the preferred approach. Its black color aids in identification and UV resistance in exposed routing paths. The 48-inch stick length allows a single piece to cover long conductor runs or to be cut down into multiple shorter sections as the job requires. Sold in a header-pack quantity of 25 pieces per unit of measure.

Key Features

• Thin-wall FP-301 construction balances electrical insulation, flexibility, and chemical resistance
• 1/8 inch nominal diameter suits small-gauge wire terminations and splices
• 48-inch length per piece allows full-run coverage or field-cut segmenting
• Black color for routing identification and basic UV resistance
• Suitable for industrial and military-specification wiring applications
• Pack of 25 pieces minimizes per-job restocking trips

Compatibility

Designed as an OEM-style thin-wall heat shrink sleeve compatible with standard 1/8 inch diameter wire and cable insulation applications in industrial, commercial, and military wiring assemblies.

Installation Notes

Licensed electricians and qualified industrial technicians should de-energize and lock out the circuit before applying heat shrink tubing to any live wiring. Use a calibrated heat gun rather than an open flame to activate shrink; apply heat evenly by moving the gun along the length of the tubing to prevent scorching or uneven wall thickness. Follow applicable NEC guidelines for insulation protection and conductor bundling. Ensure the tubing is centered over the splice or termination before applying heat, as repositioning after shrinkage has begun is not possible.
