50 To 500Pcs Heat Shrink Solder Seal Wire Connectors Kit Waterproof Butt Electrical Terminalsinsulated Splice Marine Automotive

Description: Solder Seal Heat Shrink Wire Connector Kit, Crimp-Free Waterproof Electrical Splicing Terminals for Fast, Reliable Wire Repair and Connection Features: 1. Tool-Free Simple Operation: Pre-installed low-melting point solder ring melts evenly under mild heat, no crimping tools or professional skills required, greatly simplifies the wire splicing process and saves operation time for both professional electricians and DIY users. 2. IP67 Grade Waterproof Sealing: Dual-wall structure with polyolefin heat shrink outer layer and hot melt adhesive inner layer, shrinks at 3:1 ratio after heating to form a fully airtight seal, effectively blocks water, dust and corrosion, eliminates short circuit risks for wet and outdoor working scenarios. 3. Superior Flame-Retardant Insulation: High-quality flame-retardant polyolefin material for the outer tube, meets UL electrical safety standards, provides excellent high/low temperature resistance and insulation performance, prevents electric leakage and fire hazards to guarantee wiring safety. 4. Clear Color-Coded Size Marking: Different color sleeves (red, blue, yellow) correspond to different standard wire gauges, allows quick size matching without extra measurement, reduces wiring errors and improves work efficiency for bulk wiring projects. 5. Stable Low-Resistance Conductivity: Tinned copper inner contact core has outstanding oxidation resistance and high conductivity, forms a firm, low-resistance connection with all types of copper wires, avoids poor contact issues to ensure long-term stable power and signal transmission. Specifications: Category: Electrical Wire Connector Kit Material: Dual-wall flame-retardant polyolefin heat shrink tube, pre-tinned solder ring, tinned copper contact, hot melt adhesive Size: Suitable for 22-10 AWG wires (red for 22-18 AWG, blue for 16-14 AWG, yellow for 12-10 AWG) Color: Red, Blue, Yellow, Transparent Application: Automotive wiring repair, marine electrical maintenance, household circuit renovation, electronic device assembly, outdoor lighting installation, industrial wiring projects Quantity: 50/100/120/150/200/280/300/500Pcs Note: 1.
