Gabriel
Verified Buyer
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
William
Verified Buyer
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!
Brad
Verified Buyer
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.
Kevin
Verified Buyer
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.
Stanley
Verified Buyer
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....
Michael
Verified Buyer
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.
Fred
Verified Buyer
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.
Ryan
Verified Buyer
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
