It provides a better finish for electrical connections and offers mechanical and anti-abrasive protection to cables and other electrical components. Ideal for protecting and insulating solder joints or splices, shielding them from the elements. Specifications: - Shrink ratio: 2:1 - For 4.0-6.0 mm² cable - Ideal for shrinking, sealing, soldering, and connecting two cable ends in a single operation. - Very easy to use; simply place the stripped wires into the solder sleeve and heat to achieve a perfect joint. - Transparent heat shrink with tin core and silicone ends for optimal sealing. - Shrink temperature is 80°C and tin solder melts at 160°C, can be used with a heat gun or stripper.
