3M 7000133538 FP301 Heat Shrink Tubing 1/16 in Black 25pc

Product Description

The 3M 7000133538 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable electrical insulation, physical protection, and chemical resistance in demanding environments. Sized at 1/16 inch recovered diameter and cut to 48 inch lengths, these tubes are supplied in a 25-piece header pack. FP-301 thin-wall tubing delivers a consistent shrink ratio and clean recovered finish suitable for wire bundling, insulation of solder joints, connector backshells, and general wire harnessing. Electricians, panel builders, and aerospace or industrial technicians are the primary installers of this product.

This tubing is suited for both industrial and military-grade wiring applications where space is tight and a slim recovered wall is preferred. The 1/16 inch size targets small-gauge wire terminations, component lead insulation, and fine wire bundling tasks. The black color assists in UV identification and color-coding of harness assemblies. Each piece is 48 inches long, allowing technicians to cut to length in the field for a range of harness and termination applications.

Key Features

• Thin-wall FP-301 construction provides a balance of electrical insulation and physical protection
• 1/16 inch nominal recovered diameter suits small-gauge wire and component lead applications
• 48 inch stick length allows field cutting to required dimensions
• Black color supports harness color-coding and UV identification
• Rated for industrial and military wiring environments
• Supplied in a 25-piece pack for job-site convenience

Compatibility

Designed as an OEM-style thin-wall heat shrink solution for small-gauge wire insulation, solder joint protection, and wire bundling in industrial and military electrical assemblies.

Installation Notes

Heat shrink tubing of this type is installed by electricians, wire harness technicians, and electronics assembly professionals. De-energize all circuits before applying tubing over conductors or terminations. Use a calibrated heat gun at the appropriate temperature range to achieve uniform shrinkage from the center outward toward the ends. Avoid open-flame heat sources, which can cause uneven shrinkage or damage to the tubing and adjacent components.
