Thin Wall 2:1

Thin Wall 2:1 Colored Heat Shrink Tubing

ElecDirect’s thin wall 2:1 heat shrink tubing is a general-purpose, colored HSPO tubing designed for insulation, bundling, strain relief, and wire identification in industrial, electrical, automotive, and OEM applications. Tough yet flexible, it delivers clean, professional results on wires, cables, terminals, and connectors.

With a 2:1 shrink ratio, this tubing recovers to approximately half of its supplied inside diameter when heated above 248°F (120°C), allowing it to conform tightly around cable jackets, splices, and solder joints. Our thin wall line is available in 14 standard sizes and multiple high-visibility colors to support clear circuit identification and fast troubleshooting on the job.
