Kuject 530Pcs Self-Solder Wire Connectors and Heat Shrink Tubing Kit, Waterproof Heat Shrink Butt Connector & Shrink Wrap Tube, Solder Seal Insulated Electrical Butt Splices for Marine Car Wire Joint

This turned out to be a nice little assortment of Heat Shrink Tubing and Solder Seal Wire Connectors. The 8 different sizes of Heat Shrink Tubing and 4 sizes of Solder Seal Wire Connectors will definitely come in handy for me with all the crazy projects that I undertake.The Heat Shrink Tubing is pre-cut to usable lengths and will safe me time during repairs and builds. But what I really like is the and Solder Seal Wire Connectors which are fairly new to the market. These connectors are made with clear Heat Shrink Tubing and have a band of solder in the middle and a sealing ring on each end.To use the Solder Seal Wire Connectors you just pick the appropriate size connector, insert the wires to be connected, and then heat the connector to roughly 280 degrees Fahrenheit for a few seconds. The heat melts the solder to provide a good connection and also causes the Heat Shrink Tubing and Sealing Rings to shrink, encapsulating the solder joint providing protection from moisture and oxygen; the enemies of any electrical connection.Note: If you don't already own one buy yourself a nice Heat Gun that has the ability to stand on end. Besides a million other uses, it makes working with Shrink Tubing and Solder Seal Wire Connectors much nicer.I also like the little plastic storage case these came in. It has removable dividers and two real hinges that shouldn't break like the flex hinges on similar plastic cases and has am inventory sheet showing the different Tubing and Connectors as well as their sizes.

I was installing led tape lights for my kitchen and had to cue the tape to get past some obstacles and then needed to rejoin the tape. Everything else was more than I wanted to do with soldering and such. This is the perfect solution to splicing wires. You strip the ends of the wires to be spliced, put the ends into the tube and then run the hair dryer to heat up and activate the bead of solder inside the tube and shrink the plastic ends to form a splice that will not fall apart the second you release the joint. Plus, the tubes have a water proof adhesive inside them so you can use them outside if needed. This is one of those products that is a game changer for me.

I have used heat shrink with wires for many years and seen the new product which included the solder connection with the heat shrink tubing and decided I had to have it in my collection of tools since I work on all kinds of things. Fast Delivery and ready for the next fix when it happens.

The 18 to 22 gage, especially the 18 gage solder connectors if using, apparently, older wire with a thicker outer covering will not allow you to slide the exposed wire into the soldering ring. A lot of the new wire has a cheap thinner outer covering. I did notice that one end of the connectors looks as if the outer opening is a littler larger than the other end, but that just may be a manufacturing error. Also the heat shrink are about a 1/4 to a 1/2 inch too short. Good ideas but poor quality control.

I bought these to just add as part of my tools but I have had no issues with them. Works like they are suppose to

Love these precut and sizes included. Highly recommend for rc hobbiest’s

I saw theses on a Facebook ad. I didn’t think they were a real thing. I am an electrician by trade and love to projects at home. I am current working on RGB Christmas lights and was soldering and heat shrinking the wires together until I got these! They are so easy to use and work extremely well. I will be ordering a lot more of them in the future. The heat shrink that is on the kit is nice also because it is all ready in small lengths.

Good

Hadn't ever used this type of self solder connector before, so thought I'd give it a try.Really impressed how well they work, creating a waterproof, sealed connection with solder holding it together. Have used for several applications already and will use again and again.Note - I don't think anything less than a proper heat gun will work on the solder.

Instructions would have been useful. I hadn’t used this type before & whether it was poor quality or my lack of expertise I cannot determine. But despite using up a number of pieces in trial & error they did the job eventually. I can neither diss the kit nor recommend.

Very selection of tubes. That shrink to a good fit. I havent tried the self solder tubes yet. But this pack will keep me going for a long time. Would buy again

This single purchase will cater for all of my needs for the foreseeable future. So a very satisfying "One-stop shop" solution

Easy to use
