Using a heat gun they provided and it was super easy to slip it on, twist the wires and slip it back on to solder and seal in one swoop is wicked cool! Very happy! Gave them

Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds with my heat gun till shrink tube shrunk then solder melted to wire leads...boom, done!

This solder sleeve works exactly how it is described & kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge time-saver.

After about 5 seconds the rubber material started to shrink. At about 9 seconds the solder started to melt & bond the wires. I gave the wires a firm tug & there were super tight.

I have found that if there are any wires out of alignment, there is a chance they will poke through the plastic, especially if you over-heat. per instructions, be sure NOT to squeeze the lead ring - it will crack, and then not melt to seal properly....

This is the perfect solution to splicing wires. You strip the ends of the wires to be spliced, put the ends into the tube and then run the hair dryer to heat up and activate the bead of solder inside the tube and shrink the plastic ends to form a splice that will not fall apart the second you release the joint.

I used a heat gun. It was satisfying to see the solder melt as the ends crimped down to make a strong waterproof connection. Perfect for the new LED spotlights on my Jeep.

I had rats chew through some wiring on my car used these and they work fantastic! All you got to do is just strip the wire put the wire in and use a Bic lighter to heat up the whole thing evenly and then that's it you're done. Repeat buyer

Frequently Asked Questions

What is a Butt Connector?

A butt connector is a commonly used crimp connector in electrical work. It safely terminates wires or connects one wire to another by inserting the wire into the connector.

What Types of Butt Connectors are Available?

There are several types of butt connectors — such as standard butt connectors, heat shrink butt connectors, solder butt connectors, and environmental sealing butt connectors. Each is designed for different applications and levels of protection.

How do I choose the right butt connector size for my wires?

Select the right butt connector size based on the wire gauge you are connecting. The kit includes various sizes – yellow for smaller wires, blue for medium, and red for larger ones.

Can I use these connectors for both solid and flexible wires?

Absolutely! Our butt connectors are designed for versatility, though crimping techniques may vary slightly to ensure a secure connection. Whether you're working with solid or flexible conductors, the kit ensures reliable connections.

Are these connectors suitable for outdoor use?

Yes, our butt connectors are waterproof and corrosion-resistant, making them ideal for outdoor applications. Use them with confidence in various weather conditions.

Can I use this kit for automotive wiring projects?

Absolutely! The Butt Connector Kit is versatile and suitable for automotive, marine, electrical, and electronic projects. With its durability and stability, it's a perfect fit for your automotive wiring needs.

Can I reuse the butt connectors if I need to make changes to my wiring?

While butt connectors are generally designed for one-time use, you can carefully reopen them if needed. However, using new connectors for optimal performance and reliability in your electrical connections is recommended.

Butt connectors are generally used for low to medium-voltage applications, but insulated connectors designed for copper cables can withstand higher voltages.

Always check the connector's specifications and rating to ensure suitability for your specific voltage requirements.

How Long Does Shipping Take?

Our shipping typically takes 3-5 business days in the USA and 7-10 business days in other parts of the world.
