Butt connectors come with a wide variety of names. They can be called butt splices, wire connectors, wire butt splices, butt crimps, or just plain butts. Either way, butt splices come in a variety of configurations. How do I choose the correct splice for my application?

Stripping both ends on the wires you are going to connect by 5/16", placing one wire in butt connector and using the wire strippers, it has a little concave half circle with a smaller nipple usually above the dirrerent wire gauge stripping section that squeezes the butt connector onto the wire. You could also use a pair of pliers, but doesn't do a great job. Give it a good squeeze and a tug on the wire to make sure it is holding. Do the same with second spliced wire into other end of connector.

Vinyl insulated butt splices are typically the most economical of the insulated wire splices. Use these when no special protection or characteristics is required.

Nylon insulated butt splices provide higher temperature and better durability than vinyl. They also have a seamless crimping barrel for maximum crimpability. Our seamless nylon butt connectors come with either a straight or flared barrel insulator.

For the maximum protection against environmental exposure, use Heatshrink Butt Splices to completely seal the splice.
