• ✔【 EASY IDENTIFICATION - APPLICATION AREAS 】The colour codes of these heat shrink tubes enables easy selection for the correct application. You can check the size chart on the product box, measure your wire, and select the correct connector. These shrink tubes can be used in a wide range of area. Due to high waterproof, these tubes are commonly preferred in automotive sector as well as marine sector. Solder Seal Wire Connectors can also be used in the house, and school.
  • ✔【 WATERPROOF 】This heat shrink tube has two layered, highly durable insulation. Polyolefin and hot melt layers provide protection against water and prevents any wire damages. Polyolfin tube shrinks with heat and provides sealed structure to protect the wire inside.
  • ✔【 PREVENT HEAT SHRINK TUBE BURNS 】 Stronger and more durable hear shrink tube of NoraTech prevents burns and melting of solder sleeve. Both solder and seal butt connectors are manufactured to avoid any burns or melting during heating.
  • ✔【 COMPLIANT WITH ALL RELEVANT STANDARDS 】 Solder seal wire connectors are compliant with ROHS, ISO 9001:2008, SGS and CE standards. All connectors are IP67 waterproof.

Absolutely perfect for what I needed. I was putting new trailer lights on a boat trailer, and planned to solder the wires and heat shrink them to help protect them, then I saw these that would do both in one simple easy operation, they worked perfectly and very easy, solder melted to connect wires and heat shrink to help keep moisture out. These will come in very handy for many small electrical jobs, great product that works as designed. Fast and simple!

It is a great product for my garage. I like to play with tools in my leisure time and this wire connector will be good piece in my toolbox.

That was the best wire connectors. I used them for mu project and worked great.

These are the bomb! You can make nice soldered, waterproof connections in seconds with just a cigarette lighter! I have not melted through the insulation even once. I make two little hooks on the two wires to be joined and fasten them, then slide the tubing over them. You just heat it up until the solder melts and BOOM! You've got a great connection! I used these to wire up my boat trailer and tail light harness....just took a few minutes, no hassle. I'm thrilled!

These connectors are excellent. I thought it would be easy to use but it was way easier than I thought and it works great. They melt easily for connection, no hassles! I strongly recommend this practical tool!

These are the best. I used them in a bunch of different places while installing speakers etc into my car. Make sure you have a heat gun and get the solder super hot!

like everything dislike nothing. if you are make a repair to a harness, you can solder the splice together and insulate it at the same time. I have been making up harnesses and repairing them for years. this does it in one step. its fast, easy, and you have a good connection, one you won't have to deal with again.

With this product connection is solid. Very easy to use and work perfectly. Never used this kind of connecter before and i wish i could have found this earlier. Absolutely time saver.

The design is very well thought out and executed. On each side of the solder joint there are small colored sleeves which is for a purpose. They shrink quickly and hold the two wire ends together as the rest of the magic is happening (wires are NOT falling apart while in process). These also seal each side of the connection solidly, even more than the shrink tube .

These things are awesome! As I said in the title, this is such a clean solution for wire connections. I'm an electrical engineer and building prototypes is a huge part of my job, and I can say that I truly look forward to using these connectors.
