User questions & answers

Question:	Do these have the adhesive inside as well
Answer:	Wow, so many clueless reviews. Heat shrink can and does contain heat activated adhesive sealant. It does not affect the connection at all, only seals to prevent water intrusion on marine applications such as wiring a bilge pump. I do not know if these have it but you will see a small amount ooze out if it does.
Question:	what temperature is needed to shrink these? Will a hair blow dryer work or is heat gun needed
Answer:	Hair dryer, heat gun, lighter, mini torch all work.
Question:	Are you certified to use them at 120/127 volts
Answer:	Wire size and material determine maximum current and loss due to heat (ignore above comment). Insulation determines maximum voltage. 120 volts is American household voltage. These are designed for marine and automotive applications which are typically 12 volts, sometimes 24 volts, and rarely 48 volts or other voltage. I would verify with manufacturer what the maximum voltage the insulation can take is. I repeat, these are not designed for household use, and I have never heard of those voltages in a marine or automotive application.
Question:	What crimp tool is needed to crimp these
Answer:	Make sure to use a crimped for coated connectors. If you puncture the coating they will no longer be waterproof. If that doesn't matter the regular butt connectors are way cheaper. Use these for wet applications and marine for sure.

User questions & answers

Question:	Can you use solid wire too
Answer:	Sure
Question:	What is the amperage rating when rated at 240V
Answer:	Depends more on the wire size, but I would think less than the wire itself unless you mechanically twist the joint, too. Solder as the primary conductor in the joint isn't the best if the joint is likely to get heated by the current.
Question:	Do you crimp these or just twist the wires together and heat shrink them? if no crimping, how strong is it compared to crimping and heat shrinking
Answer:	You will just need to twist the wires together and heat shrink them. Solder inside the connector will melt and bond the wires together. The connection is almost as strong as crimping and heat shrinking. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation, creating a strong seal
Question:	What temp do I use on the heat gun
Answer:	Low flame

User questions & answers

Question:	Do these contain low temp Solder? In other words, you just heat, not crimp? The picture says heat, the instructions say crimp
Answer:	The heat is for the heat shrink that's already on the connectors. You still have to crimp the terminal. Side note: I found these to be low quality. They'll work, but I wouldn't trust them for anything critical.
Question:	Do you need to crimp the wire or just heat shrink to make connection
Answer:	Crimp the wire, then apply heat to shrink the insulation down
Question:	Are these copper as advertised
Answer:	They dont look like copper, but I didnt have them tested or anything.
Question:	Were is my package says it was delivered
Answer:	Stolen obviously

User questions & answers

Question:	what type of heat gun or torch is best of shrinking
Answer:	I have used a 1500 watt heat gun and also a mini butane torch. Both work but the mini torch covers a smaller surrounding area.
Question:	Is the width of the red 22-18 ga. male quick disconnects
Answer:	I can't answer this because of the Amazon Gestapo's
Question:	Are these adhesive-lined
Answer:	the adhesive is only on the ends not thru the whole connector.
Question:	Can these be used by crimping? Or only heat
Answer:	They are crimp fittings with the plastic part heat shrinkable. A cigaret lighter works great to shrink it to the wire.

User questions & answers

Question:	What is the voltage rating on heat shrink
Answer:	I don’t know the exact rating but it is made for low-voltage like 12 V or 24 V connections. Not 120 V use.
Question:	Will these work for RC cars. For the battery , motor and electronic speed control
Answer:	i do not see why they would not so long as you have the right size for the wire diameter and enough room to heat them without effecting other parts of the RC car.
Question:	Do you have to ceimp the connector or is it just heat shink and its done
Answer:	Just heat up. That's it
Question:	Why cannot we get a mutikit with bloody 8 awg butt solder joins? why such an issue
Answer:	I would guess that they do not have enough solder, in the joiner, to be effective. Or there is not much call for that gauge wire, they can not be all things to all people. For that, strip the wires, place some shrink tubing on one of the wires, solder, let it cool, slide the shrink tube over, shrink it. Some times, when there is sufficient wire length, I place two different size shrink tube,. shrinking the smaller one first, letting it cool. The slide the larger one over the other.

Question:	Can you use these for speaker wires? Thanks
Answer:	Dear Customer Yes, you can use it for the connection of speaker wires when the wire size is suitable. In other words, if the size of your speaker wire is (A.W.G.:26-10), then you can use our wire connectors to connect the speaker wire. Please note that our connectors are heat shrink wire connectors, NO NEED TO CRIMP for it and it can not be crimped, just heat shrink it via heat gun and then you can finish your project. Thank you Kuject customer service team
Question:	are wire connectors the same thing as butt connectors
Answer:	Dear Customer,  These are solder seal wire connectors, rather than butt connectors. This is the heat shrink butt connector here: https://www.amazon.com/dp/B07B518GCJ. You can check they are difference via the link above. For let you know their difference eaiser, we compare these two kinds of connectors from 4 aspects as follow:  1. Simplicity of Operation. For joining the wire with heat shirnk butts, you need a heat gun and plier, but for the solder seal coneecotrs, you just need a heat gun, as there is no need to crimp. So, the solder seal connector will be easier to use.  2. Waterproof Resistance. Both of them are waterproof, but there are two hot melt waterproof adhesive rings in the solder seal connectors, which will make it get a better waterproof and seal performance.  3. Flexibility of Use in The Confined Space. The solder seal connectors can be bent after connection and just need a heat gun to control the temperature to finish the joint, so it is more flexable and eaier when joining wire in the confined space.  4. Price. On Kuject, 210Pcs heat shrink butts is $19.99 ($1 for 10 piece) , and 120Pcs solder seal wire connectors is $16.99($1.42 for 10 piece) . The price is cheaper for every piece of the heat shrink butt connectors.  In conclusion, the solder seal connectors have a better performance than the heat shrink butts although it is a little expensive. So, we will recommend to use the solder seal connectors in most case, but it still depend on your needs. Besides, there are two kinds of butt connectors in the market: crimp butt connector & heat shrink butt connector. Maybe you refer to the crimp butts, so we also talk about the crimp butt connector here. The appearance of crimp butt is almost same as the heat shrink butt, but the tube outside of crimp butt connector is made by nylon, so they can not be heat shrinked and not waterproof, which can not be used outdoor or humid area, just only can use indoor and dry space.  These are the introduction of the three type of connectors above, hope our answer help you. Best wishes,  Kuject customer serivce team
Question:	How many wires can I fit on one connector? I think I’ll be using 14 gauge
Answer:	At least (2) will fit into the largest of the (3) size connectors in this kit. (3) 14 gauge wires might not.
Question:	Can I use the largest size to crimp 3 14 gauge stranded wires together
Answer:	Sure could. These are the fastest and the slickest crimp I've seen yet.
Question:	Are these heat shrink nut
Answer:	No they are not heatshrink! They are crimp pieces.
Question:	Is the metal copper or aluminum
Answer:	It is aluminum. Hope this helps. :)

Upgrade Overheat Resistant Material of The Shrink Wrap Tube

It is hard for beginners to control the heat shrink temperature when first to try these heat shrink wire connectors. Sometime, exorbitant temperature make the wrap tube melt but the solder ring still not melt, which result in failing to connect the wire. So, Kuject upgrade and use special material in the transparent tube, which can prevent the tube melt when it increase to a high temperature in a short time.

Solderless & Crimpless - Save Much Of Your Time

Compared to the crimp heat shrink butt connectors, you don't need to use the crimper to crimp the item when using the solder seal wire connectors, save one step to do it. And compare to the old way use solder and heat shrink tubing, you don't need to use the solder iron to solder the wire, also save one step for soldering. So, the solder seal wire connector is solderless & crimpless, which can save much of your time when you are using it for your project. Besides, you can also use them in hard to reach or limited space environments easily.

Step 1

Thread the connector to one of the wires and then twist the two conductor together.

Tips: Please make sure the end of the wire that you strip out is nice and clean (shiny).

Step 2

Move the connector to the middle of the conductor.

Tips: Make sure you strip out the end of the wire long enough for them to overlap one another and stay in the area of the solder sleeve.

Step 3

Apply heat to the connector slowly and evenly with a heat gun with reflector nozzle until it melt with the wire.

Tips: Some of our customers can use lighter to finish the joint, but we strongly recommend to use a heat gun with REFLECTOR NOZZLE to heat shrink the connector, especially for beginners.

Finished Item Display

Note: In some case, a solder ring mark will be left after the tin ring was melt, but it doesn't mean the tin ring is not melted and it fails. As long as there are enough tin melt with the copper then it will hold up strongly, it is unnecessary to pursue 100% meltdown of the solder ring. You can stretch it to test after the connector cool down.

• ● CONVENIENT TO USE - NO need to crimp. Transparent sleeve provides precise inspection when strip and insert wires inside. Color-coded tubing makes it easy for you to pick up for use.
• ● DURABLE CONNECTION - Tubing reduces in size and solder will melt and flow through the stripped wires, ensure strong holding. Your wire will never slip out of the connector.

Question:	What temperature should someone use to melt the solder but not burn the waterproof plastic/shrink wrap
Answer:	I USED LOW TEMP SETTING ON MY HEAT GUN.. BUT I WATCHED CLOSELY TO SEE WHEN THE SOLDER MELTED AND PROMPTLY REMOVED HEAT. WORKED WELL.
