Overview

The NSI Industries Easy-Twist C12-N-B 1000-count bag of nylon closed-end wire connectors delivers fast, secure, and UL-listed connections for 12-10 AWG pre-insulated wires in tight spaces. Engineered with a corrosion-resistant nylon 6/6 shell (UL 94V-2 self-extinguishing) and an internal copper crimp sleeve, these connectors ensure a low-resistance, vibration-resistant joint without twisting or taping wires. Rated for 300V maximum and temperatures from -40°F to 221°F (-30°C to 105°C), they meet UL 486C standards (E155027) and are CSA certified. The compact design fits applications where space is limited, such as appliances, lighting fixtures, HVAC systems, and industrial control panels. Installation is tool-assisted: strip wires, insert into the connector, and crimp with adjustable pliers or a 1/4" drive socket tool (included in bulk bags). Color-coded for easy identification and featuring a threaded funnel entry, these connectors eliminate loose connections and flashover risks. Each 1000-count bag includes installation tools, making them ideal for high-volume electrical and electronics projects requiring reliable, code-compliant terminations. The closed-end nylon connector features an internal metal crimp sleeve that can be tightened over twisted pre-insulated wires to form a safe and secure join. Their compact design is useful for applications in tight areas or anywhere else you need to connect wires.
