What are Butt Splices?
Butt splices are crimp connectors used to safely connect one or more wires to another wire. It depends on which style of butt splice you are using and the task at hand. Step-down butt splices are meant to connect a higher gauge wire to a lower gauge wire. They could also be used to connect two or more smaller gauge wires to a single wire. Their ease of use and economical pricing make them very common in electrical systems.
When selecting which type to get, pay special attention as to whether they are epoxy lined or not. Why is this important? Many manufacturers do not line the interior of their butt splices with a melt-able glue. This epoxy reacts to heat and expands creating an environmentally sealed connection. This is useful in marine conditions or other environments where hazards may be present. To use, heat the ends of the butt splice with the proper tool after crimping and you're done. Epoxy lined is only available with heat shrink butt splices. The alternative to epoxy lined is either vinyl or nylon insulation or non-insulated. These types are useful in situations where the environment is not a direct concern. Pacer Group’s large inventory of butt splices are offered in heat shrink, nylon, vinyl and non-insulated.
