## Questions & Answers

**Q: are wire connectors the same thing as butt connectors?**
A: 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,

**Q: Photo w/ all the connectors lying outside the box shows about 25 of 12/10 connectors but the box/label shows only 10 are provided - which is correct?**
A: There are only 10, the first photo of 25 is dishonest.

**Q: Are these connectors UL listed?**
A: What is UL certified mean?-UL Certified. A certificate, issued to a manufacturer for one of its products, which indicates that the product has been tested in the US by the Underwriters Laboratories, Inc. (UL) and has met UL requirements.

What you should know about UL certification?-UL Certification means that a product has undergone rigorous testing to ensure its safety standards are up-to-date. UL provides a number of services for a business—including validating, testing, inspecting, auditing, and certifying products and various businesses around the world.

What is the cost to be UL Certified?-The fee, paid to UL, is often in the range between US$5,000 to 15,000. Then again, this is for he services provided by UL, and not including product development costs.
China Imports -UL (Underwriter Laboratories) develops electronics safety standards for the United States, and provide related testing, certification and auditing services.- Unlike the EU, where importers must comply with a set of harmonized electronics safety standards – American electronics importers are free to choose which standards to comply with.-UL standards are developed for specific electronic products, or components, such as cords, batteries and plugs.

**Q: I need to join wires when installing the new radio for my car, is it safe and reliable for using these kind of self-solder wire connectors?**
A: Dear Customer,

Our item is IATF16949:2016 Listed, this is a certification of International Automotive Task Force. Automobile company like Ford, General Motors and Chrysler Corporation require that only product which go through the certification IATF16949:2016 can be used as parts to repair their cars, so you can use our connectors at ease.

Besides, compare to the tradition method that wiring with the solder iron, using our self-solder wire connectors will be much faster and easier, all you need is just a heat gun to heat the connectors.

Best wishes,

Used the smaller sizes. I needed a little more heating than I expected, but then I had my work to do outside. In the wind, 10 degrees C outside. Connection seems excellent to me.
