High-Performance Tinned Copper Core : 99.9% pure tinned copper ensures optimal conductivity with minimal voltage drop and heat generation. The seamless design guarantees secure connections, preventing slippage and shorts - perfect for automotive, marine and electrical applications.
No-Solder, Tool-Friendly Installation : Simply strip wires, insert into the connector, crimp with pliers, and apply heat (using a heat gun or lighter). The transparent sleeve allows for easy inspection, while color-coded sizes simplify identification. No welding required!
Waterproof & Flame-Retardant Protection : Marine-grade polyolefin tubing with a 3:1 shrink ratio and adhesive lining creates a 360° waterproof seal. Dual-wall insulation resists flames and environmental damage, making these splices safe for underground, marine, or outdoor use.
Durable Against Physical Damage : Reinforced tubing withstands rodent bites, abrasion, and mechanical stress. The thick tinned copper core and seamless barrel design ensure long-lasting, vibration-resistant connections—even in harsh conditions (-55°C to 125°C).
Versatile Kit for Diverse Projects : Includes 1000pcs connectors for automotive, boat, home, and industrial wiring. Reliable performance with a full shrink temperature of 130°C and superior conductivity for secure, low-resistance connections every time.
