About this item

  • BETTER WATERPROOF SOLUTIONS: Double wall design, Hot Melt Adhesive inside ensures wires strongly connected and prevent wires slipping from the terminal; Polyolefin outside tubing provides insulation and improves pullout strength
  • PREMIUM SOLDER SEAL RING: Tubing reduces in size, the enough solder will melt and flow through the stripped wires, ensure a long lasting connection for your application
  • ABRASION RESISTANCE HEAT SHRINKABLE TUBE: Premium tube materials are specially designed to be used in harsh environments. Protect the wires and cables from abrasion, cutting, scuffing and low impact situations
  • EXCELLENT WIRE CONTACT: The tin barrel provides increased current flow, and ensures less voltage drop, preventing wiring failures and reducing equipment downtime
  • WIDE APPLICATIONS: Excellent stability, water resistance and electrical conductivity provide durable connection for motorcycle, off-road vehicles, lawn tractors, RVs, fish finder and marine application. Widely used on multiple projects of your Christmas lights, ships with high waterproof requirements motorcycle stereo, boat electronics, equipment switches

  • Rugged and puncture resistant.
  • Waterproof.
  • Resistant to abrasion, stretch and vibration
  • Heat activated adhesive
  • Greater tensile strength
  • All materials are heat resistant
  • Suggest used a 1500W heat gun.

hot melt adhesive

  • Create a waterproof seal
  • Resistant to stretch and vibration
  • Color coded for easy identification

solder

  • Starts to melt at lower temperature (280 °F)
  • Prevents burns in the heat shrink tubing
  • A more efficient alternative to soldering

heat shrink tube

  • Offer protection to the wires and cables from abrasion, cutting, scuffing and low impact situations.
  • Create cable entry seals, offering environmental sealing protection.

Strip

Strip wire insulator with a proper length and insert wires into the solder sleeve of proper size

Twist

Twist the conductor together and move the connector to the middle of the conductor

heat

Evenly heat by a heat gun (better with reflector nozzle) until it melts

Water proof and amazing quality and easy to use and would recommend getting like 2 or 3 boxes because when doing wiring you tend to use a lot!

I like these solder connectors I did have to go a size larger , I strip about 1/2 inch on both wires slip on connector to 1 wire then twist/ weave wires together then slide connector over twisted wires then use heat gun or torch. Strong and weather proof splice!

These have been working great in place of the old fashion wire connectors. I did buy a butane torch just for heating these. I tried using just a lighter, but it the heat was not uniform across the connector. The butane torch is nice as it allows you to adjust the amount of heat that is being applied.

Ask my husband and he will get so excited. He put together two sets of lights and extended the plug. He cant stop telling his friends how easy it is. Cheap for so many varieties of size

These things are excellent and easy to use. Way better than those stupid crimp connectors that you usually have to put heat shrink over anyway and since these are soldered, they're way stronger and faster to use. Highly recommend using a good heat gun and not a lighter.

Had a need to connect a numbe ofr individual auto cable inline connections. Stripped wire ends, gave a touch of a flux pen to each and of the wires, twisted ends and push end into either end of suitable connector. Then used a battery powered heat gun shrink the tube and melt the wire connection. Had to do this for eight connections and all worked. (Note: due to the cables each being connected to existing fixtures it was not possible to twist the wires together before heat application. No probs.

Fast. easy. Shink seal. Good quality. I will never go back to butt connectors. Use a heat gun!

These do work quite well, however you do need to use the correct source of heat. A good or reasonable quality heat gun with a deflector works well, it will get the solder to melt and makes a good solid connection that will test with no major increase in the circuit resistance. I tried a mini-torch with heat deflector in my pre-use testing, its just too is too hot, too fast. By time the solder melts it over heats the shrink tube which then fails. If your looking for a system to same time, this may or may not be the best choice, it is a bit faster than soldering and covering with shrink tube. But you will need to take your time to get a good connection you cant rush the heat. If you have some electronics flux available adding a very small amount to the wires before you slide the connector over helps with the flow of the solder.
