Butt splices are an easy way to create or repair an electrical connection. They are simple to use and built to last. Seamless barrel butt splices come in three varieties of insulation. You can get them in nylon, vinyl or non-insulated. How do you use seamless barrel butt splices? It's easier than you think. Start by cutting and stripping your wires to the proper length. Now, if you look inside the butt splice you will see an indentation. Your wires should butt up against that. So insert your wire making sure they butt up to the indentation. Crimp using the proper tool. The proper tool guarantees the correct amount of pressure. This ensures a solid connection. Now simply repeat on the other side and you're done. We would strongly recommend performing a tug test to ensure that the connection is solid. To do this simply grab both wires coming out of the butt splice and gently tug two or three times. See, I told you it was easier than you thought.

When using butt splices, the first step is to make sure you have properly stripped the wires to the correct length. If you look inside the butt splice you will see an indentation your conductors should butt up against. Insert the wire making sure the insulation touches the butt splice. Otherwise you run the risk of a weaker connection. Now, the splice is crimped with the proper tool. This crimp bends the connector around the wire which creates a solid connection. Next, repeat the process on the other side and perform the tug test to make sure the wires dont pull out. And now you've created a durable connection. Butt splices are used for their rapid installation and durability. Other methods of connection may not offer the same level of protection.
