Time saver! There is a better way to do a car repair. How long did it take you to solder your wire? Has it ever failed after installation? Well, this solder shrink butt connector set will solve the problem. We used high quality materials to make the connectors, using durable plastics and 30% glass content shrink tube to reach higher heat resistance and shrink tightness. The product passed IATF16949:2016 listed certification test.


You just finished soldering the last wire on your new project, and it's time to cap it off with a nice, clean look. You reach for a pair of heat-shrink butt connectors to finish the job, but then you realize that you don't have any more solder left to use if you want to connect two wires together. You're out of luck unless you can find another source for some.

This is where Kuject comes in. Kuject is an innovative new product that provides a quick and simple alternative to soldering or crimping wires together when you need to make a connection that has to be waterproof and heat-resistant. The connectors have built-in heat-shrink tubing that shrinks around the wire after it's been connected with a pair of pliers or a screwdriver, making them completely waterproof and safe for use in marine environments. You can even put them in boiling water without melting!

Kuject connectors are made from high-temperature materials that can handle temperatures up to 500 degrees F, so they'll be able to take the heat whether they're being used on your car engine or under your kitchen sink. They're even IATF16949:2016 Listed, which means they've been tested by an independent third

What I Like

I have worked on electronics for years. I have soldered / heatshrinked wires of all sizes. I have used different crimp connectors over the years as well. I did not expect these would work as well as they show on the videos. I was wrong. They work very well. I had the best results using a heat gun. I tried a lighter. This worked somewhat. Or mostly? But I was

What I Like

What can I say? It's a terminal connector, they are pretty hard to screw up. I could knock it 1 star because 2 of the blue connectors were in the yellow bin when it showed up, but unlike most reviews on Amazon, I understand that is not the connector's fault. But the shrink wrap does add a little razzle dazzle to it, and pretty much the only reason why I bought these.

Heat Shrink Butt Connectors, 100Pcs 16-14 AWG Blue Insulated Waterproof Electrical Wire Connectors Automotive Marine Grade Wire Crimp Terminals Butt Splices, Ideal for Boat, Truck, Stereo - Blue

heat shrink wire connector kit

Good day everyone, welcome to my review of the Heat Shrink Butt Connectors, 100Pcs 16-14 AWG Blue Insulated Waterproof Electrical Wire Connectors Automotive Marine Grade Wire Crimp Terminals Butt Splices, Ideal for Boat, Truck, Stereo - Blue. I have been in the music business for many years now (and I can't believe I just said that. Ha), and was looking for some high-quality butt connectors to use on a job the other day… That's when I came across these. With a ton of awesome features like "seamless barrel design" and "tinned thick red copper", they seemed like a no brainer…so I ordered them without hesitation!


If you've ever crimped a wire connection, you know how easy it is to accidentally cut the insulation off the wire and expose some to the elements. Sealing up those exposed parts is just as important as making sure the two wires connect, which is where these heat shrink butt connectors come in. They act as insulation barriers to protect your wire from sun damage, water damage, and wind damage while also providing a secure connection between two wires.

For this project, we're using heat shrink butt connectors with a thickness of 0.20-inch and an inside diameter of 0.19-inch for 16 gauge to 18 gauge wire. The connector design itself is seamless, meaning it's less likely to fray or break when crimping down onto the wires. They're rated for 300V AC and 600V DC service with a maximum continuous operating temperature of 105 degrees C (221 degrees F) and are made with tinned thick red copper barrels that are plated for corrosion resistance and polyolefin heat shrink tubing that meets flame retardant standards. The heat shrink tubing has a shrink ratio of 3:1, so it's capable of shrinking down to one third of its size after it has been heated—this makes for a more secure connection at both ends of the splice

What I Like

I like the clean, durable weatherproof crimp connections that are available from C&S. I use LOTS of the standard red, blue, or yellow heat shrink butt connectors for wiring 22 to 10 gauge...and I would use even more of the smaller ones if I had known they existed. Well, now I do know...and I bought some. I'll be buying more in the future.

What I Like

I read the negative reviews before purchasing these and it seems that they were disappointed that the heat shrink burned through when trying to get the solder to melt. I found that the key was regardless of the heating source, which I used a heat gun on low, you need to keep the gun moving around the solder point with constant back and forth motion.

What I Like

I needed this kit for a pontoon boat re-wiring project. This well-made, thin, clear plastic kit has 200 pieces. (Yes, I counted every one!) I like how the wire gauge numbers were stamped on the metal AND the heat shrink. The heat shrink is THICK and you will definitely need a heat shrink gun.
