Connect Your Wires Safely With the Best Butt ConnectorsLast updated: 14 Jul 2022
Unlike Marvel’s Electro, we cannot just walk away from getting electrocuted, let alone gain superpowers from it. So, we need to make sure we keep all the wire connections in our home 100% protected. Unfortunately, the twisting and taping method isn't enough because the tape can fall off or the wires can get pulled apart. Soldering is a no go for most people too, as it requires way too much effort. Thankfully, butt connectors are perfect for this job.
These little tube-like connectors not only hold onto the wires securely once crimped but also provide great insulation. They are also pretty easy to use, which is another plus. That being said, finding quality butt connectors isn't as easy thanks to the multitude of options available online. So, to help, we made this guide to buying the top butt connectors of 2022 so you can navigate the market better.Show contents
Buying Guide: Butt Connectors
What Are the Benefits of Using Butt Connectors?
They are safer
Butt connectors are much safer than simply twisting two wires together and taping them over. This is because the tape can come off over time or the wires can be pulled apart. Butt connectors provide a full insulation tube to go around the wire, covering it completely to keep you safe.
They save time
One of the major downsides of soldering is it requires too much time and effort. Thankfully, butt connectors are so much quicker to use. All you need to do is to pop the wires into the connector, crimp it, and heat it — the whole process takes just a few seconds.
Terms Related to Butt Connectors Explained
You will find that some butt connectors are IP-rated. This rating tells you how water and dust-proof these connectors are. Generally, a higher IP rating means the connector has better waterproofing, but you can use guides explaining what each IP rating means. The IP rating of a butt connector is usually stated in its product description.
A butt connector usually has compatible gauge sizes written on it. This tells you how big of a wire you can use with a specific butt connector size. The gauge size of a wire is usually written on it or stated on its box.
What to Look for When Buying Butt Connecters?
A butt connector with low conductivity can ruin your wire connection. So, only go for the options that feature a core tube made with a highly conductive material such as copper and brass. This way, you won't have to deal with dropping voltages or bad connections. You can check what materials a butt connector is made of by taking a look at its product description.
It is generally best to get a pack size with twice the amount of pieces you need, so even if the connector gets ruined because of a mistake, you’ll still have another one to use. Also, ensure the pack you buy has the right connector size that you need. You can check both the pack and connector sizes in the product description.
How We Chose the Top Butt Connectors
Flared barrel design
We ensured all the butt connecters we chose for our list had flared and wide barrel edges. This makes it much easier to put the wires in so you don’t feel like you are threading a needle. You can check if the butt connecter you chose has flared edges or not by looking at its pictures or reading its reviews.
We also made sure all the barrel connectors on our list are color-coded. This makes it much easier to pick the right connector size from the kit with just a glance, saving you time and effort. To check if the butt connectors you chose are color-coded or not, you can take a look at the product pictures or description.

People Also AskedQ: Can I crimp butt connectors using pliers?
A: You should not crimp butt connectors using normal pliers as you may end up crimping too hard or too soft. Instead, it is best to use crimpers for this purpose; these tools are specifically made to deform materials so you can get the optimal connection.Q: Can I use a lighter to shrink a butt connector?
A: You should never use a lighter to shrink the butt connector after installation. Doing so could burn the connector. Consider using a heat gun for shrinking the butt connector safely and more efficiently.Q: Can I connect two different wire sizes using a butt connector?
A: Yes, you can connect two different wire sizes using a butt connector. Just make sure the wires aren't loose as that may lead to a safety hazard. You can check this by pulling on the wires gently once they're crimped.
