2:1 Heat Shrink Tube (40pk) is universally applied for the insulation of connections or for the end-handling of electric wire, for the insulation of soldered points on resistors and capacitors, for the identification and encapsulation of electric wire, for the corrosion-proofing of metallic rods or tubes and for the protection of antennas. Heat-shrinkable tubes are also used for the corrosion-proof and waterproof connection of fiber optic cable.
