10PCS 4 Gauge Wire Connectors with Heat Shrink Tubing, Battery Terminal Ends, Tinned Copper Ring Terminals for 4 AWG - for Automotive, RV, Solar &

【Heavy-Duty Construction for Harsh Environments】:Built with thicker copper and a heavy tin plating to combat corrosion where standard terminals fail. This robust design ensures stable electrical conductivity and long-term reliability in high-humidity, salty air, or under-hood environments, perfect for off-road vehicles, farm equipment, and coastal applications. 【Weatherproof Seal with Adhesive-Lined Tubing】:Each terminal includes a 3:1 heat shrink tube with hot melt adhesive for a complete environmental seal. When heated, it forms a waterproof, dustproof, and vibration-resistant barrier, providing ultimate protection for battery connections, solar panel wiring, and outdoor power installations. 【Foolproof, Professional-Grade Installation】:The integrated inspection window allows you to visually confirm perfect wire insertion before crimping. Simply match the ring terminal to your wire gauge (AWG), crimp firmly, slide the tubing over, and apply heat. This easy-to-install design guarantees a secure, gas-tight connection every time. 【Engineered for Demanding Automotive & Power Applications】:Ideal for critical 12V/24V connections that demand durability. The extra thickness provides superior mechanical strength for battery terminals in RVs, golf carts, and utility vehicles, as well as connections in solar arrays, generator sets, and outdoor lighting systems. 【Premium Kit, Guaranteed Performance】:A complete, professional connection solution. Includes high-purity tinned copper lugs and industrial-grade heat shrink tubing. We stand by the quality craftsmanship. For optimal results, please verify the AWG size and use a proper crimping tool. Our support team ensures your satisfaction. Professional-Grade Electrical Connection Solution Welcome to our high-performance tinned copper ring terminal series. Designed for reliable, durable, and safe connections, this product is the ideal upgrade for automotive modifications, solar panel systems, RV electrical work, and outdoor power equipment. Core Material & Craftsmanship Advantages Heavy-Gauge Pure Copper: Constructed from thicker copper for superior mechanical strength and current-carrying capacity, ensuring a tight, vibration-resistant connection. Heavy Tin Plating: The thick tin coating provides excellent oxidation and corrosion resistance, maintaining stable conductivity over time—especially critical in high-humidity or high-temperature environments. Professional Heat Shrink Tubing (for 10PCS & Trial Pack): Includes 3:1 dual-wall tubing with hot melt adhesive inner lining. When heated, it forms a waterproof, dustproof, and shock-resistant seal for complete environmental protection. Specifications & Compatibility Precise Fit: This is a 4 AWG ring terminal, perfectly sized for 4 wires. Standard Hole Size: The ring hole is sized to fit common standard bolts. Foolproof Installation: The built-in inspection window allows you to visually confirm the wire is fully inserted before crimping, ensuring a perfect connection every time. Easy 4-Step Installation Guide Select: Choose the terminal that matches the AWG marking on your cable. Strip: Strip approximately 3/8 inch (10mm) of insulation from the wire end. Crimp: Fully insert the bare wire strands into the terminal barrel and crimp firmly using a proper crimping tool. Seal (for kits with tubing): Slide the heat shrink tube over the connection. Apply heat evenly with a heat gun until the tubing shrinks tightly and adhesive seals both ends. Wide Range of Applications Automotive / RV: Battery terminals, car audio systems, light bar wiring, auxiliary power. Renewable Energy: Solar panel connections, wind turbine wiring, battery bank links. Outdoor Power Equipment: Golf carts, utility vehicles (UTVs/ATVs), lawn tractors. Other Uses: Power distribution boxes, trailer wiring (non-marine), industrial control cabinets, and various DIY electrical projects.
