Connect and Seal your Wires

without crimping or terminals!


  • WATERPROOF - Unique dual walled design; polyolefin tubing on the outside and hot melt adhesive inside. When heat is applied, the tubing shrinks and joins the cables together. 
  • EASY TO USE - Simply position the TWO stripped wires into the solder sleeve and apply heat to finish the connection. The solder will gradually flow, and the insulation tubing will shrink down, creating a waterproof seal.

  • EASY IDENTIFICATION - Color-coded tubing makes it easy to identify the right size connector for every application. Measure your wire, and easily choose the right connector by looking at the wire size chart on the box.
  • GREAT FOR PROFESSIONAL OR EMERGENCY USE - Melted Solder ensures wires strongly connected and avoids wires slipping out from the terminal.

Customer Review

"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" - Maria Stewart

"These things are priceless! Used to wire in my aftermarket Head unit radio. 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

"Holy crap these things are easy to use! I've used them to re-route my speaker outputs from my car radios head unit to an amp and then back to the speakers. It was a lot of splicing, in a very tight space. I had to use a BBQ lighter instead of a hear gun due to the limited quarters. Controlling the heat was a little more tricky that way. If I fired the solder for too long the flux would burn throug" - Evan
