Customer Reviews

Wonderful product!

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!

Gabriel

Verified Customer

Work excellent!

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!

William

Verified Customer

Huge Time-Saver

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.

Brad

Verified Customer

Superb!!!

After about 5 seconds the tubing 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.

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
Can I use them for marine wiring like on boat?
Yes! Solderstick is IP67 waterproof and can withstand harsh conditions.
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), these are an excellent choice. They will keep the joint dry and make it far less susceptible to corrosion under the hood.
How long does shipping takes?
Our shipping typically takes 3-5 business days in the USA and 7-10 business days in other parts of the world.
Is There a Warranty or Guarantee With Solderstick Products?
If you are not completely satisfied, we are here to make it right. We offer a 90-day money-back guarantee on our products. Our customer support team is also always ready to assist with any questions or concerns.
