About this item

  • Insulated and waterproof: the electrical wire terminal comes with outer polyolefin tube and inner hot-melt ring, which can effectively improve waterproof performance, so it is very popular in the automotive and marine industries
  • Practical design: these solder seal wire connectors are different from ordinary heat-shrinkable tubes, and designed with solder ring and do not need crimping; The solder seal terminals are transparent and can be accurately inspected when the wires are stripped and inserted inside
  • Simple operation: you can just put 2 stripped wires into the solder sleeve and heat it with a hot air gun, and the insulating tube will shrink with a shrinkage ratio of 2:1 to form a waterproof seal, so as to complete the connection
  • Wide range of uses: the insulated butt splices are useful tools to provide good protection for wires, which are often applied in automobile, ship, marine, motorcycle and vehicles, and also applied for scientific wiring projects
  • Package includes: you will receive 300 pieces 22-18 AWG red heat shrink butt connectors, with heat shrinkable, waterproof and conductive properties, which are enough to meet your various needs

Low melt solder and works good! Just what I was expecting. Used a few right away to see if they were good or junk and they are good! Thanks! Came in a box loose, I put them in a small zip lock bag.

I use these for my exterior illumination props and they are easy to use and I have used them for over a year now.

These Solder Seal Connectors are perfect for repairing small wires that become frayed or repairs around the house. All you have to do is expose 1/4" of wire at each end and slide the wires into each end of the tube, meeting the wires in the middle, under the silver solder. You then heat the solder with any heat source - hair dryer, heat gun, lighter, flame, etc and then move along the tube to shrink it to the wire and seal it closed. The connection is water resistant if done correctly. Every toolkit needs these in various sizes for easy repairs.I used it on a car dashcam GPS module that had too much cable to conceal, so I cut out the unneeded wire and made the job much neater. You should pick up good wire strippers on Amazon as well to strip wires of all sizes. The process takes seconds looks great if you finish by covering the work with black heat shrink tube.

Tried a total of 10 trying to do 1 wire, solder will not melt and heat shrink burns away before solder tries to melt. complete waste of money

Ease of use is incredible, but you rely on the low temp solder for the mechanical connection. At first I tried to make a lineman slices with these, but the heat shrink is too soft and protruding slivers of wire will punch right through it.. these have to be put together to a butt splice with a little bit of overlap, relying on the mechanical ability of the solder to hold things together
