Product Description

The Plastic Wire Nut is a small insulated connector used for joining the ends of wires. Its plastic shell contains a conical spring that secures several stripped wires by twisting them together, inserting them into the nut, and applying slight force with hand or pliers.

The outer layer of nylon is flame-retardant, resistant to burning, and also waterproof and anti-loosening. After installation, just check the color—gray, blue, orange, yellow, or red—to determine the wire gauge capacity of the terminal.

Product Feature

Installation without tools and fast work: it can be installed by hand without screwdriver, adhesive tape, etc. A novice can install one in a few seconds. For the production line of batch assembly, with pneumatic crimping pliers, hundreds can be installed in an hour, more than three times faster than adhesive tape.

Replace adhesive tape, clean and tidy: After wrapping the electrician adhesive tape for a long time, the tape will turn black and stick to the hands. When removing it, scissors need to be used to cut it. After the plastic wire cap is installed, the surface is clean and can be removed during maintenance. It is much more convenient than using adhesive tape and will not leave any residue on the wire.
