Wire Connectors

Wire connectors join conductors quickly and safely, delivering secure electrical connections for home wiring, automotive repairs, marine installations, and industrial maintenance. Quality electrical connectors reduce arcing, resist vibration, and maintain continuity under load, boosting reliability and helping you meet code. Look for UL-listed parts with clear voltage and temperature ratings so your splices, terminations, and pigtails stay safe in junction boxes, control panels, and tight spaces. The right connector shortens install time, simplifies troubleshooting, and keeps projects clean and professional. Properly sized connectors also minimize voltage drop and heat buildup over time. Select reusable lever styles to streamline maintenance and upgrades.

• Wire nuts (twist-on caps) for solid or stranded copper; color-coded by AWG.
• Push-in and lever connectors for fast, tool-free splicing and easy rework.
• Crimp types: butt splices, ring, spade, and bullet terminals for secure terminations.
• Heat-shrink and waterproof options with adhesive lining for outdoor and marine.
• Solder seal connectors combining solder, flux, and tubing for field repairs.
• High-temperature and ceramic connectors for fixtures and appliances.
• AL/CU-rated connectors for aluminum-to-copper transitions.

Match materials and ratings to the job: tinned copper or tin-plated brass for conductivity, nylon or polycarbonate insulation for heat and impact. Size to wire gauge (AWG), solid vs stranded, and circuit amperage. For damp locations, choose IP-rated, gel-filled, or adhesive-lined designs. Color coding speeds selection.

Cut square, strip to the marked length, and avoid nicking strands. Use a ratcheting crimper with the correct die; perform a firm tug test. For twist-on caps, torque until snug. Apply even heat with a heat gun, verify continuity with a multimeter, and label the circuit.

Browse wire connectors, electrical connectors, terminal blocks, ferrules, and quick-disconnects, plus crimpers, heat guns, heat-shrink tubing, and cable ties to build safer, longer-lasting electrical systems with fewer callbacks and faster installs.
