Colorful Heat Shrink Tubes 140 pcs – Bright Insulation and Organization for Your Cable Projects

Assortment of 7 Diameters in 5 Vibrant Colors for Marking, Protection and Aesthetics

This heat shrinkable tube set includes multiple polyolefin heat shrink tubes in various colors for versatile electrical insulation, mechanical protection, and color coding of wires and cable connections. Heat shrink tubing contracts when heated to form a snug, protective covering around wire joints and exposed conductors.

Key Features:

• Material: Polyolefin (PE) – durable and flexible insulation material.

• Shrink Ratio: 2:1 – shrinks to about half its original diameter when heated.

• Colors: Mixed vibrant and standard colors for easy wire identification and coding.

• Temperature Range: Shrinks around +70 °C to +110 °C with excellent performance in typical electrical applications.

• Use Cases:

  • Insulating electrical wires and cable joints

  • Protecting soldered connections

  • Color coding and marking cables

  • Mechanical protection against abrasion and moisture

How It Works: Place the tubing over the wire or connection, then apply heat (hot‑air gun, soldering iron with warm air, etc.). The tube will shrink snugly around the wiring, providing a robust protective layer.
