3M 7010399006 Heat Shrink Tubing FP301 3/64 in Black

Product Description

The 3M 7010399006 is a thin-wall heat shrink tubing sold in a 10-piece pack, each piece cut to 6 inches in length. Based on the FP301 series, this tubing is designed for electrical insulation, wire bundling, strain relief, and color-coded identification of conductors and harnesses. The 3/64 inch recovered diameter makes it suited for very small-gauge wire and fine conductor applications. Electricians, harness builders, and low-voltage technicians install this tubing using a heat gun to achieve a clean, snug sleeve over terminations and splices.

This tubing is commonly used in residential, commercial, and industrial electrical work wherever a lightweight, reliable insulating sleeve is needed on small-diameter conductors. It is also used in panel wiring, automotive harness repair, and control system wiring where a thin-wall profile is preferred over adhesive-lined alternatives. The black color aids in identification and provides a clean finished appearance in visible wiring runs.

Key Features

• Thin-wall FP301 series construction provides reliable electrical insulation with minimal added bulk
• 3/64 inch recovered diameter suits fine-gauge wire and small conductor terminations
• Pre-cut 6 inch lengths reduce prep time in the field or on the bench
• Black color supports conductor identification and blends into standard wiring assemblies
• 10-piece pack format keeps inventory organized and reduces waste on smaller jobs

Compatibility

Designed as an OEM-style thin-wall heat shrink sleeve for use on small-gauge electrical conductors and wire harness applications requiring a 3/64 inch recovered diameter.

Installation Notes

Licensed electricians and low-voltage technicians typically install heat shrink tubing as part of conductor termination or splice work. De-energize all circuits before applying tubing over any live termination point. Use a calibrated heat gun rather than an open flame to shrink tubing evenly and avoid damaging the sleeve or adjacent insulation. Follow NEC guidelines for insulation requirements applicable to the circuit voltage and environment.
