Set of 70 thickened copper ring terminals with 80 double‑wall heat-shrink tubes — designed for long-lasting electrical connections, high-temperature use, and reliable protection against moisture and environmental damage. Key benefits High conductivity and durability: Thickened copper eyelets provide excellent electrical conductivity and mechanical strength for demanding conditions and high-temperature applications. Moisture and environmental protection: Double‑wall heat‑shrink tubing seals and insulates the crimp, offering robust protection against moisture, corrosion, and abrasion. Reliable mechanical design: Closed pad construction ensures secure crimps; the built‑in inspection window makes wire insertion fast and accurate, reducing installation errors. Versatile sizing: Includes 70 ring terminals in sizes 2, 4, 6, 8 and 10/12 to cover a wide range of wiring needs across multiple projects. Ready-to-use kit: Supplied with 80 heat‑shrink tubes to match the terminals so you can crimp and protect connections immediately. Practical uses and applications Automotive repairs and upgrades: Secure battery, starter, or grounding connections that must tolerate vibration and heat. Marine and outdoor electrical systems: Use the double‑wall shrink protection to prevent corrosion and moisture ingress in boats, trailers, and exterior installations. Home and industrial wiring projects: Ideal for solar inverters, HVAC equipment, appliances, and control panels where dependable, insulated ring connections are required. What’s included (specifications) Terminals: 70 ring cable lugs — sizes 2, 4, 6, 8, 10/12 Shrink tubing: 80 pieces of double‑wall heat‑shrink tubing for sealing and insulating crimps Material: Thickened copper eyelets for high conductivity and durability Design features: Closed pad design for secure crimps; inspection window for easy wire insertion Performance: Suitable for high‑temperature applications; provides moisture and environmental protection when heat‑shrunk Installation tips Strip the wire to the correct length, insert through the inspection window to verify position, crimp firmly using the appropriate crimping tool, then apply heat to the tubing until it shrinks and the adhesive liner seals the connection. Match tubing size to the terminal for a tight seal and consistent protection. This kit delivers durable electrical connections with enhanced protection and practical sizing for a wide range of maintenance and installation tasks.
