50 PCS Solder Seal Wire Connectors


  • Free shipping and returns

  • Lifetime Warranty

  • REVOLUTIONARY IP67 WATERPROOF SOLDER & SEAL TECHNOLOGY - A waterproof seal is created easily by placing stripped wires into the solder sleeve and applying heat. Dual-walled heat shrink tubing with hot-melt adhesive prevents wire corrosion. You will never have to worry about water damage.
  • THICKER TUBING TO PREVENT BURNS - A low-temp solder sleeve with thicker heat shrink tubing prevents solder melting through the insulation tubing.
  • COLOR-CODED AND COMPLIANT WITH ALL STANDARDS - For easy identification, the connectors are color-coded along with a handy wire size chart located on the box.
  • AN AMAZING SOLUTION FOR HARD-TO-REACH AREAS - Solder seal wire connectors work excellently in limited-space areas, as solder and seal electrical terminals do not need crimping.

What can I say? The product is really amazing! I never tried using any product like this before, but I am thinking of using this still in the future. High quality and it works as described. When I tried using these connectors for my wires, it didn’t disappoint me. I love this kit. A great buy!

Best connectors!

I used mini torch and heat gun on each test and the results are both great. The best connectors I’ve used to date. I began heating both ends to secure the connection and heat the solder at the middle. The connections are perfectly sealed. Looking forward to buying again!

Great choose

These connectors are great! I have used them for my boat wiring project and it looks awesome. The heat shrink tubing is thick and very nice. It is also a quick way to secure waterproof connections. I would say that this is an excellent option to standard crimp heat connectors.
