3M 7000132601 Heat Shrink Tubing Assortment 1/4 Inch 21 Piece

Product Description

The 3M 7000132601 is a heat shrink thin wall tubing assortment pack designed for wire insulation, bundling, and strain relief in electrical and low-voltage wiring applications. The pack includes 21 pieces total — 3 pieces each of 7 colors — all cut to 6-inch lengths at a 1/4-inch diameter. FP-301 series thin wall tubing shrinks with applied heat to form a tight, insulating sleeve over conductors, terminals, and splices. This assortment is a standard bench and van-stock item for electricians, HVAC technicians, and control wiring installers who need quick color-coded identification across multiple circuits.

FP-301 thin wall heat shrink tubing is suited for residential and light commercial electrical work, control panel wiring, HVAC low-voltage circuit repairs, and general wire harnessing. The multi-color format supports color-coded circuit identification without stocking individual rolls. Each 6-inch piece is ready to cut or use as-is for standard terminal and splice coverage.

Key Features

• 21 pieces total — 3 pieces each of 7 distinct colors for color-coded circuit identification
• 1/4-inch nominal diameter, 6-inch pre-cut lengths
• FP-301 thin wall construction for low-bulk insulation over terminals and conductors
• Applies with standard heat gun — no special tooling required
• Lightweight pack at 0.1 pounds — practical for field kit or van stock

Compatibility

Designed as a general-purpose thin wall heat shrink sleeve for use on 1/4-inch nominal wire, terminal, and splice applications in electrical, HVAC low-voltage, and control wiring installations.

Installation Notes

Heat shrink tubing is installed by licensed electricians and HVAC technicians working on de-energized circuits — always confirm power is off and circuits are locked out before applying tubing over live terminations. Slide tubing over the conductor or splice before making the final connection, then apply a heat gun evenly along the length until the tubing conforms fully. Avoid open flame as a heat source, as it can scorch or unevenly shrink the tubing. Follow applicable NEC requirements for insulation rating and conductor protection.
