haisstronica 660PCS Heat Shrink Butt Connectors Kit, AWG 22-10, Waterproof, Tinned Copper | 3 Colors, 3 Sizes

• High-Quality Tinned Copper Core- The heat shrinking connector copper core uses tinned copper, which is easier to flatten and grasp the wires, to enhance electrical conductivity
• Polyolene Pipes- The connector shell is made of high-quality polyolefine and will not break the insulation layer when being pressed. They are resistant to corrosion and chemical erosion
• Sufficient Hot Melt Adhesive- The connector contains sufficient hot melt adhesive, which generates more adhesive to wrap the wires during use, so the wires will not be easily detached
• Easy to Use- Compared with other connectors, the heat shrinking connector has a larger selection of fitting tools and is easier to operate in the compressing process, suitable for DIY
• 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

• Strip approximately 0.5 cm (1/4 inch) of insulation from the ends of the wires you need to connect. Ensure the exposed copper strands are clean and free of damage. — Prepare Wires
• Insert the stripped wire ends into the appropriate sized haisstronica butt connector. Use a proper crimping tool to firmly crimp the metal barrel onto the wires, ensuring a tight mechanical connection. — Insert and Crimp
• Using a heat gun on a medium setting, evenly heat the connector. Continue heating until the polyolefin tubing shrinks tightly around the wires and the internal hot melt adhesive flows out, creating a complete seal. — Apply Heat
