Butt splices are a type of connector used to safely connect one or more wires to another wire. Their economical pricing and ease of use make them common in electrical systems. Heat shrink butt splices create an environmentally sealed connection to handle harsh conditions. They are simple to use. First, make sure you have correctly stripped the wires to the proper length. Inside of the butt splice, you will see an indentation your wires should butt up against. Be careful to make sure that the butt splice and the wire insulation are touching. Otherwise, you run the risk of damaging the wire due to exposure. So, the stripped wire is inserted into one side of the butt splice and crimped with the proper tool. This crimp bends the connector around the wire creating a solid connection. Next, you simply repeat the process on the other side. Alternatively, you can crimp the other end creating a dead end. Before you heat it, don't forget the tug test. Once your wire is properly crimped, apply heat to the butt splice working outward. Be careful not to burn the butt splice or the wire insulation. And now you've created a durable, environmentally protected connection. Remember, butt splices are useful for their rapid installation and durability. Other methods of connection may not offer the same level of protection.

Terminals are a necessary element in any electrical systems. These heat shrink butt splices provide a durable, rugged, environmentally sealed connection. They are designed for use with wires between 22 AWG - 10 AWG.
How do you use heat shrink butt splices? Well, you start by prepping your wires. This includes cutting and striping the wires to the correct length. Each butt splice has an indentation inside of it in the center where your wires should meet. So now, you insert the wire into the butt splice until the tip touches the indentation. Using the proper tool, you will crimp the side of the butt splice creating a solid connection. Repeat this process on the other side. Now, perform a tug test to make sure that the wires do not pull out. Once you are satisfied, use the proper heat gun or torch to correctly heat the outer heat shrink. If you see bubbles or discoloration in the wire insulation or the heat shrink you are using too much heat. That or your tool is too close.
Why use heat shrink butt splices? Heat shrink butt splices offer the highest level of environmental protection available. By utilizing these types of splices you are creating a moisture proof barrier that will last. Heat shrink butt splices protect connections from physical abuse and abrasion. They also protect from water, salt and other corrosive compounds.
