3M 7000031588 Heat Shrink Tubing 133 Piece 7 Color Kit

Product Description

The 3M 7000031588 is a multicolor heat shrink tubing assortment kit designed for electrical insulation, wire bundling, and strain relief across a wide range of trade applications. The kit contains 133 individual pieces of FP-301 dual-wall heat shrink tubing spanning seven colors and six sizes, making it a practical bench stock for electricians, HVAC technicians, and low-voltage installers who need quick access to the right size and color without ordering individual spools. FP-301 tubing delivers a reliable balance of electrical, physical, and chemical resistance properties suited to production wiring, field service, and panel work.

This assortment is well suited to residential and light commercial electrical work, control panel assembly, HVAC control wiring, and general low-voltage installations where color-coded identification and durable insulation are required. The seven included colors support standard color-coding practices, and the range of sizes covers the most common conductor gauges encountered in field and shop environments. Installers working across multiple trades will find this kit useful as a shared bench supply.

Installation Notes

Heat shrink tubing is applied by licensed electricians, HVAC technicians, and low-voltage installers as part of wiring termination and insulation work. De-energize all circuits before applying tubing to conductors. Use a calibrated heat gun rather than an open flame to shrink tubing evenly and avoid damaging insulation or adjacent components. Follow applicable NEC and local code requirements for conductor insulation and identification.
