Polyethylene heat shrinkable solder cable connectors, for the joining of multi and solid strand copper cables. Terminals consist of Polyethylene, solder ring with flux, glue ring adhesive. Operating temperature -45 to +125, Shrinking temperature +125 to 180, Maximum Voltage 600V. Heat Shrink Solder Butt Connectors are ideal for joining cables without the need for crimping. When properly shrunk the solder within the butt flows connecting your wires together, whilst the melted adhesive rings in combination with heat-shrink tube provide a seal resistant to water and other contaminants. The translucent tubing allows visual inspection ensuring the cables are inserted safely and correctly as well as providing excellent abrasion and strain resistance.
