Crimp. Solder. Shrink. The Multi-Link butt connector is crimped for maximum reliability, soldered for strength and conductivity, and heat-shrink sealed for superior durability and protection. The high quality brazed seam crimp connector provides a secure mechanical connection. The pre-fluxed, low temperature solder delivers superior current flow and tensile strength. The translucent, adhesive-lined heat shrink tubing allows for visual inspection and provides a seal against corrosion.
