Heat shrink tubing is commonly used for connecting electrical cables, insulating soldered points in resistors and capacitors, marking and protecting electrical wires, protecting metal rods or pipes from corrosion, and safeguarding antennas. These waterproof heat shrink tubes are used for connecting fiber optic cables.

This is a halogen-free, flexible, flame-retardant heat shrink tubing that is free from Pb, Cd, Hg, Cr+6, PBB, and PBDE. It can be used in any enclosed space where a flame-retardant, halogen-free environment is required, such as in subways, skyscrapers, transportation vehicles, and cargo ships. The heat shrink tubing is rated for UL 600V and marked with an F designation.
