Upgrade your wiring with this 180PCS Solder Seal Wire Connectors Kit designed for fast, dependable splices in marine, automotive and household jobs. Each connector is a heat-activated solder sleeve: when warmed with a heat gun, the solder ring melts into the strands while the heat shrink tubing grips and seals the insulation. The result is a strong, insulated join that helps prevent pull-out, shorts and corrosion even with vibration.
