Real Pros Speak Out!

Soldering was always the messiest part of my projects, until I tried SolderStick. It's simple, it works, and it doesn't require a steady hand or a prayer. For someone who's into getting things done without the drama, this was a game-changer.
Mike, Hardware Engineer

Alright, picture this: me, under a car, wrestling with wires and a soldering iron that's got two settings—'cold as ice' and 'molten lava.' Then I found SolderStick. My new best friend skips the hassle, burns, and bad words. Connections are a breeze now, and I don’t miss the old iron one bit.
Gary, Car Electrician

I just finished rewiring my utility trailer with these. So easy and gratifying. I've always hated crimp type butt connectors, so I would always solder my connections and cover them with heat shrink, tedious and time consuming. These take the trouble out of all that.
Alex, Marine Technician

frequently asked questions

Could i use a small butane or propane torch instead of a heat gun?

Definitely! Just don't get it too close as you will over melt the shielding

WILL SOLDERSTICK WORK WITH DIFFERENT TYPES OF WIRES?

Absolutely! Whether you're 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, remember heat both ends of the sleeve and they will seal water tight.

WHAT'S THE MAXIMUM WIRE SIZE SOLDERSTICK CAN HANDLE?

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

I just need single size wire connector, where can i get it?

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

Can these be used in an engine compartment of a vehicle example (Ford F350 Diesel)?

As long as you keep a reasonable distance from the exhaust components such as pipes, manifolds, turbo then these are an excellent choice as they will keep the joint dry and far less susceptible to corrosion under the hood.

CAN SOLDERSTICK CONNECTORS BE USED FOR OUTDOOR PROJECTS?

Yes, they're ideal for outdoor use! SolderStick’s waterproof design ensures connections stay protected against the elements, making them perfect for garden lighting, outdoor sound systems, and more.

How long does shipping takes?

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