Butt Splice Connectors Are a Great Way to Make a Safe and Reliable Electrical Connection
When connecting wire ends together, the most common method is to solder. While it can be an effective solution, the high heat can cause injury and damage to equipment if done wrong.
Butt splice connectors are a simpler, more cost-effective and safer way to do the job. They provide a compression-type connection that is stronger than the wires themselves.

There are different types of butt splice connectors that meet different needs and applications. It is important to select the right one for your particular project and installation factors. The type and size of butt splice connector that you choose depends on the wire size, wire stranding (single or multi), the wiring material, and other considerations.
Insulated Wire Terminations
For high-voltage applications, insulated terminals are the best option because they are approved to UL/CUL standards and can handle voltages up to 600 V. They are primarily designed for copper cables and are tin-plated to resist corrosion.
Nylon Splices
A nylon splice is a more rugged butt connector than vinyl because it provides a better solvent and temperature resistance. It also comes with either a flared or straight insulator end opening that promotes maximum strength.
Butted Seam Connectors
Relatively inexpensive, butted seam connectors are formed when metal is stamped, rolled and butted to create the connector barrel. These are often used with stranded wire and require crimping after the termination has been made to ensure a secure connection. Brazed seam connectors, on the other hand, are more expensive and provide a strong termination that can be used with solid or stranded wire.
