Frequently Asked Questions

What Is a Solder Wire Connector?

A solder wire connector is a heat shrink tube with a low-temperature solder ring in the middle. It connects solder wires without the need for specialized tools.

Both sides of the solder ring have a ring of heat-activated adhesive that creates a seal when heat is applied.

I Just Need a Single Size Wire Connector. Where Can I Get It?

You can get it here. Simply select the kit size and color, and you are done! We will ship single-size wire connectors depending on the connector size you pick.

What Is Included in the Solderstick Waterproof Solder Wire Connector Kit?

The Solderstick waterproof solder wire connector kit includesvarious sizes of solder wire connectorsdesigned to create waterproof and durable wire connections.

Could I Use a Small Butane or Propane Torch Instead of a Heat Gun?

You can definitely use a small butane or propane torch instead of a heat gun! However, you should not get it too close since you can over-melt the shielding if you are not careful.

Will Solderstick Work With Different Types of Wires?

Absolutely! Whether you are working with copper, aluminum, or a mix of materials, SolderStick connectors are designed to provide a strong, reliable connection across a variety of wire types.

Are These Connections Weatherproof?

Yes, these connections are weatherproof. However, remember to heat both ends of the sleeveto create a lasting watertight seal.

What’s the Maximum Wire Size Solderstick Can Handle?

SolderStick connectors can accommodate wire sizes up to 10 AWG. For specific projects, refer to our sizing chart to find the perfect fit for your needs.

Can These Be Used in an Engine Compartment of a Vehicle Example (Ford F350 Diesel)?

Yes, if you keep a reasonable distance from the exhaust components(such as pipes, manifolds, and turbo), then these are an excellent choice since they will keep the joint dry and make it far less susceptible to corrosion under the hood.

Can Solderstick Connectors Be Used for Outdoor Projects?

Yes, Solderstick connectors are also ideal for outdoor use! Our waterproof design ensures connections stay protected against the elements, making them perfect for garden lighting, outdoor sound systems, and more.

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
