Safety and Reliability: Wire splicing connector is made of high-quality insulating material flame-retardant nylon PA66, which is flame-retardant, corrosion resistance, aging resistance, high-pressure resistance, long service life, preventing electrical leakage, safe and durable.The built-in copper can be used up to ambient temperatures of 105C, better conductive properties. High Efficiency: Quick wiring, no tools required, and no damage to the core, can be fitted in seconds to stripped cables. Also, dont worry about twists between the wires. Just lift up the lever, insert the stripped wire, and press the lever closed, hold tight, and make a solid connection.Koverflame connector will make the job much easier, offering you a clean and beautiful wire organization. Compatibility: Wire nut kits are widely applied to can be used for the motor, electrical control, power supply, home appliance, lighting, machinery, and other wire connection parts, connect any combination of solid, stranded, and flexible copper wires, ideal for compact and complex applications. Product Features: Wire nut connector instead of traditional electrical tape and electrical butt connectors twist-type, technological innovation reduces wiring time, making connections more efficient with low maintenance.
