• HIGH-QUALITY COPPER CORE:Heat shrink butt connectors use a copper core with a higher thickness rating.This makes your connection project safer and better meets our customers’ quality needs
• HIGH-QUALITY HEAT SHRINK:Translucent heat shrink tubing provides high tensile strength and resistance to stretch and minimize mechanical damage.The thick barrel ensures a strong crimp every time.The inner wall of the heat-shrinkable tube has enough hot melt adhesive to ensure waterproof performance reliability.Your wire will never slip out of these heat shrink wire connectors
• RECOGNIZABLE:Tubings of varying colors with easily recognizable wire gauge markings. Simply measure the wiring, and by checking the mark of wire gauge of the polyolefin tubing, then you can quickly choose the right connector
• WIDE APPLICATIONS: High quality 3:1 shrinkage tubing has a heat-activated sealant lining to provide complete secure seal. It's flame-retardant, waterproof, and can be used underground. Compliant with all electrical standards, Perfect for marine and automobile applications, whether you are working on your boat, Vehicle, Home or scientific project

• Prepare Wires — Strip approximately 6-8mm of insulation from the ends of the two wires you need to connect. Ensure the stripped ends are clean and free of damage.
• Insert and Crimp — Insert one stripped wire end into each side of the butt connector's barrel. Use a proper crimping tool to securely crimp the barrel onto both wires, ensuring a tight mechanical connection.
• Apply Heat — Using a heat gun on a low-to-medium setting, evenly heat the butt connector. Start from the middle and move towards the ends. The polyolefin tubing will shrink tightly around the wires, and the internal adhesive will melt to form a waterproof seal.
• Inspect Connection — Allow the connector to cool completely. Inspect the connection to ensure the tubing has shrunk tightly and no wires are exposed. The seal should be secure and waterproof.
