Posi-Products® connectors help make your electrical connections fast, easy, and reliable with no crimping, soldering, or messy tape. Just strip your stranded wires, insert them in the caps, and then hand tighten the two caps together - the wire ends get locked between opposing cone shapes to create a water-, dirt-, vibration-, and heat-proof housing. You get a strong, low-resistance electrical connection, and you can reuse the connectors, too. Posi-TwistTM connectors replace old-fashioned wire nuts and crimp caps with stronger, more reliable connections. This package contains 18 connectors for 14- to 24-gauge wires.
