Solder/Shrink Heat Shrinkable Terminals & Connectors: Ring Terminals (Solder/Shrink): The solder splice connectors consist of a fluxed solder ring with a heat shrinkable insulation sleeve which, when heated, provides a completely soldered, strain relieved, and encapsulated termination. Advantages of using \"Solder/Shrink\" Terminals and Connectors Translucent, adhesive lined polyolefin tubing allows visual inspection, prevents corrosion, and provides a waterproof seal . Colour coded tubing with wire gauge imprint provides easy identification of the correct part for the job . A soldered connection provides superior electrical current flow and tensile strength . Easy installation with pre-measured soldereliminates the crimping process.
