About This

• Superior Materials & Conductivity：Made of 99.9% pure thickened tinned red copper cores, combined with marine - grade polyolefin heat shrink tubing and adhesive - lined double - wall insulated tubing. The thick copper reduces voltage drop, offers high current and low heat, ensuring firm crimp and great conductivity, preventing short - circuits.
• Easy & Quick to Use：No soldering needed. Strip wire insulation, insert into connector, crimp with a tool, and heat with a heat gun or small blowtorch in seconds. Wire - gauge - marked terminals are easy to identify, and the transparent sleeve aids inspection.
• Exceptional Waterproof & Flame - Retardant：With a 3:1 shrink ratio, the heat - activated adhesive creates a 360 - degree waterproof seal. The double - wall insulated tubing is flame - retardant, and the marine - grade terminals can be used underground.
• Wide Application & Ample Quantity：Comes with 500 red AWG22 - 16, 500 blue AWG16 - 14, and 500 yellow AWG12 - 10 connectors. Suitable for automotive, marine, electrical, and electronics industries, with an operating temp of - 55°C to 125°C, shrink temp of 80°C, and min full - shrink temp of 130°C, meeting daily needs.
• Durable, Safe & Reliable：Polyolefin tubing has high tensile strength, resisting mechanical and rodent - bite damage. Thick tinned copper and seamless barrel ensure wires stay in place for a secure connection.
