Best Butt Terminals in 2022

Last update: January 20, 2023

Are butt connectors OK?

Yes, butt connectors are okay to use. They are commonly used to connect two wires together.

Can you use butt connectors in a car?

Butt connectors are commonly used to connect two wires together in a car. The most common type of butt connector is the insulated butt connector, which is used to connect two wires that are not exposed. The other type of butt connector is the uninsulated butt connector, which is used to connect two wires that are exposed.

Can you use crimp connectors for house wiring?

Crimp connectors are commonly used to join two pieces of electrical wire together, but they can also be used for house wiring. While crimp connectors are not as strong as soldered connections, they are much easier to install and are just as reliable.

Can you use crimp connectors on solid wire?

Crimp connectors are not recommended for solid wire because they can cause the wire to break.


Kuject 210pcs Heat Shrink Butt Connectors, Crimp Electrical Wire Connector Waterproof Insulated Butt Splice Terminal for Automotive Marine Boat Truck Trailer Stereo Wire Joint Review:


These were purchased to connect the harness adapter to the new stereo wiring plugs during the installation of a new automobile stereo. The speaker wires on the new stereo were too thin for these and would easily come out, so I used the 18-22AWG diameters and doubled the wire over on itself, which worked perfectly. The wires in the Metra harness adapter were thick enough to be properly crimped on.I used my old, incredibly inexpensive crimp tool on them without any problems; it didn't even break through the connectors' insulation. Although I used my heat stripper gun at its highest level, it still took some time for the heat shrink to shrink and the wire became quite hot as a result. I had to be careful not to touch the wire after that.



330PCS Haisstronica Heat Shrink Butt Connectors-Waterproof Electrical Wire Connectors-Insulated Crimp Connectors Butt Splice for Watercraft, Electrical,Electronics,Automotive (4 Colors / 4 Sizes) Review:


Always used Klein crimpers and butt connections of the vintage automotive variety. They have always operated without a hitch, and there is no reason to question the strength of their link. Even though it isn't necessary for my application, I've been really wanting to employ heat shrink because I've never liked the way they looked. Anyway, I recently invested in low heat solder connectors, which have the solder inside the tubing and are shrunk at the same time that the solder is melted. Well, these absolutely did not work for me. I refrained from leaving a negative review because I wasn't sure if my poor usage of them was the problem. However, taking this path is fantastic!In my opinion, using these connectors with specialized ratcheting style crimpers is the best option. I won't be returning ever!



540 PCS Wirefy Heat Shrink Wire Connectors - Electrical Terminals Kit - Marine Automotive Crimp Connector Assortment - Ring Fork Hook Spade Butt Splices Review:


a good product. It has a dual-wall plastic cover made of shrinkable plastic on the outside and adhesive on the inside. Heat causes the plastic to shrink (3:1) and the glue (polyolefin) to melt, creating a tight seal.A ratcheting terminal crimper, which applies the proper pressure, produces the best crimps (see further below).The kit includes a wide variety of crimps, both in terms of style and size (9 types in 3 sizes).When space is at a premium, such as on a boat or while driving far away in a car, a twin wall crimp saves the day. To conserve even more space, I take a variety of crimps in a smaller container.For the majority of general purpose activities around the boat or automobile, the 540 piece package provides enough crimp terminals. The greatest all-around terminal kit I've ever bought is this one.A single wall and dual wall crimp differ in that the glue in the dual wall produces a firmer product with less movement while also enhancing overall strength. A single wall crimp may be preferable if vibration is a problem (like in Outback Australia or Africa), as it lessens damage from corrugations and vibrations by allowing for more mobility. Pick the best alternative for the task at hand.TIPS FOR CRIMPINGHere are some tips for creating quality crimps:1. Invest in dependable terminals like the Wirefy.2. Invest in a reliable wire stripper, such as the Klein Tools 11063W Katapult Wire Stripper or the IRWIN VISE-GRIP 2078300 Self-Adjusting Wire Stripper.Buy a Ratcheting Terminal Crimper, third. The SG Tool Aid SGT18980 Ratcheting Terminal Crimping Kit is a good option if you want a range of dye heads for various projects. Iwiss produces a variety of professional crimpers.4. Using the wire stripper, trim the insulation off the wire to the proper length (note how much quicker, easier and better quality the wire stripper is compared to a pair of pliers).5. Adjust the wire thickness and the Wirefy terminal (important for good crimps).6. Insert the proper dye into the crimping tool with the terminal. I feed the wire into the terminal and carefully close the crimping tool to lock the dye onto the terminal without crushing the terminal.7. It's crucial to use the proper dye and to insert the terminal into the dye properly.8. A ratcheting crimper uses the right amount of pressure to create excellent crimps.9. Shrink the plastic cover and melt the glue using an electric/butane heat gun. I heat the object until the crimp seal is visible and a small amount of glue escapes from the plastic cover. The translucent nature of Wirefy connectors allows you to look through the plastic to check the seal.10. Enable cooling. It's done. Examine the crimp.11. Typical crimping errors: Failure to properly align the wire size with the crimp terminal, use the appropriate dye for the terminal type, and correctly position the crimp terminal in the dye jaws are examples of mistakes that might be made.12. Exercise is crucial. Before utilizing crimps in real life, practice good technique. I practice to establish a decent technique before performing a work in real life using outdated wire and cheap terminals. Test both single and multiple wall terminals to experience the stiffness variations I mentioned above.The tools may be pricey up front, but they will serve you for a very long time. The tools paid for themselves after one job I completed on my automobile. I regret not bringing them sooner!It is less expensive to purchase larger size kits like the 540 Wirefy. I divided the terminals between myself and two friends so that we could all choose from them and save a ton of money. The cost of purchasing terminals in small kits is prohibitive.The crimps have more applications than I had anticipated.



Kuject 120PCS Solder Seal Wire Connectors, Self-Solder Heat Shrink Butt Connector Waterproof Insulated Electrical Butt Splice Wire Terminals for Marine Automotive Aircraft Boat Truck Stereo Wire Joint Review:


Providing some background I've worked with wires as small as 24awg all the way up to 500 MCM (wires about 1" across), so I've dealt with a lot of splicing in my time. I've been doing electrical and electronics for over 40 years and was an aviation electronics tech in the US Navy, so I've worked on everything from simple car/truck/trailer wiring to residential/commercial electrical and electrical/electronics on military aircraft. Having said that, nothing can, in a perfect world, replace a straight, unspliced wire. You'll eventually need to connect prewired gadgets to existing wiring or repair a wire. One of the greatest ways to do this is with a solder junction, and the best method has been to add heat shrink to cover and insulate the splice. The next best option is a mechanical splice. These were mentioned in a YouTube video, so of course I sought them up on Amazon. I discovered a ton of different vendors, and the reviews ranged from one star to five stars, so I decided to get some and give them a shot. I'm happy I did because they perform well and I intend to get more. After using them and reading the reviews of complaints, I can conclude a few things.FIRST, AVOID USING A LIGHTER OR TORCH! When you can, use a heat gun. Keep in mind that these are primarily comprised of plastic with some low-temperature solder within. If you use a lighter or torch, you must be extremely careful about how near you are to the splice and how long you allow the heat to remain concentrated in one area. I am aware that not everyone owns a heat gun and that it may be necessary to fix wiring in a location without an electrical outlet.#2 Make sure the wire is clean! The reason for this is that while the solder band inside the heat shrink does contain some flux, it is not enough to etch away that corrosion and allow a good flow of wire between the stands on the two wires you are splicing. When you strip out the end of the wire, it should be nice and shiny copper, not corroded (copper turns green when corroded and in worst case scenarios, black).Advice: Be sure to strip the wire ends long enough to allow them to overlap and remain in the vicinity of the solder sleeve. Ensure that the copper is spotless (shiny). While holding the other end in place with your hand, heat one end of the wire to help it stay in place. Keep your heat source, preferably a heat gun, a considerable distance away from the splice. If the solder band isn't shrinking, move the heat source closer until it does. If the heat shrink sleeve begins to darken or burn, you're too close. A common error when using this product or just heat shrink alone is that the person holds it in one place and holds the heat source in one spot expecting it to heat the entire thing and shrink. Make sure you rotate the splice as you shrink and solder it. If the insulation on the wire starts to melt or bubble once more, the heat source is either too close to the wire or the heat has been concentrated in one place for too long. You can see the tiniest splice they've ever used to join two wires (18-20 awg copper stranded, I forget) in the photo I've attached. The splice is still visible, and the solder flowed beautifully (note the right side wire, the insulation is a little bubbled and thats my fault with the heat in one spot too long and also with that small of a gauge of wire it can heat up really quick).I bought the product despite having some reservations about it based on the reviews, and I'm pleased I did! I had originally intended to use these solely on splices that required water resistance, but after using them and observing how well they perform, I will start using them on all splices going forward. I sincerely hope that this aids others in deciding whether or not to purchase and try these splices.



TICONN 150PCS Solder Seal Wire Connectors Kit, Heat Shrink Butt Connectors, Waterproof and Insulated Electrical Wire Terminals, Butt Splice Review:


I replaced the hvac fan resistor and resistor harness in my 1988 Ford F250 pickup using one 10-12 gauge and three 14-16 gauge wires (see photo). I twisted the ends of both wires together after slipping the Ticonns on each wire and removing about 5/8" of insulation from their ends. After positioning the Ticonns over the connection, I shrank the tubing and melted the solder inside using a heat gun. When I use them, I have a very positive initial impression. If I could have determined whether the solder melted as completely as it did in the demo film, I would have given them five stars. Since I didn't want to melt a hole through the tubing, I didn't want to apply too much heat (if that is even possible). Even if some of the solder hasn't completely melted, the electrical connection is still strong. I'm happy that I can now fully utilize the heating fan in my truck. I didn't exert much force on the finished connection, but it felt sturdy enough. Only time will tell. I'll change this review to five stars if I use them on another project in the future and can verify that the solder totally melts (if changing a ranking is possible). These connectors are suggested.



50pcs Solder Seal Wire Connector, Sopoby Solder Seal Heat Shrink Butt Connectors Terminals Electrical Waterproof Insulated Marine Automotive Copper(23Red 12Blue 10White 5Yellow) Review:


Great craftsmanship and a nice range of sizes. I bought these to have them on hand for when I need them, which is pretty much always when something stops working when you live and travel full-time in a fifth wheel. It seems like everything in one of these is somehow connected to the electrical system, and because moving the trailer feels like an earthquake, things break and come loose quite frequently. I've used a few of them already, and I appreciate having them on board because every time I've used one, the results have been flawless. My 1500 watt hot air cannon melts them precisely as they should. Simply cut a short piece of each wire end you're using, insert it into the splice, melt the splice onto the wire, and then insert the other wire end into the open end of the splice. The metal center of the splice will complete the circuit, making the wire whole again. That's all there is to it; it's not even difficult. With these in the trailer and my pickup, which I use to tow the fifth wheel, I've had tremendous luck. Although I don't see myself running out of these anytime soon, I will purchase additional items identical to these from this seller if and when I do.



Haisstronica 120PCS Solder Seal Wire Connectors-Heat Shrink Butt Connectors-Waterproof Wire Connectors for Marine Automotive Watercraft Electronics Electrical Wire Connectors.Butt Splice Review:


When fixing wires, I used to solder the connection after sliding a heat shrink tube over the wire, hoping that the heat from the soldering junction would prevent the tube from prematurely shrinking. (A problem when repairing 3-wire wires since you want to remove the least amount of cord sheath possible.)These wire connectors work incredibly well. Use your wire strippers to place the two wire ends into the connector's opposing ends before heating it up. It takes a little while for the Wagner tiny heat gun to melt the solder, but it eventually completes the task. I purchased it after reading positive reviews on Amazon.These are not for you if you enjoy making simple chores more difficult than they need to be. Otherwise, they are completely worth it.



250PCS Solder Seal Wire Connectors - Sopoby Heat Shrink Solder Butt Connectors - Solder Connector Kit - Automotive Marine Insulated Waterproof Electrical Wire Terminals Review:


250PCS Automotive Marine Insulated Waterproof Electrical Wire Terminals - Sopoby Heat Shrink Solder Butt Connectors - Solder Connector KitI've been meaning to use this for a project for about five months now. Since I've been working in the microelectronics sector for so long, I've never been satisfied with crimp connectors, but getting the soldering iron out is a hassle for a few connections. I went to Amazon to check what they have to offer after seeing these advertised on Facebook. I decided to try these after carefully examining the situation. I was not let down.A little trailer that need new wiring and lights was my project. Actually a simple task. Even though I live in a desert, it does rain, and when it does, it floods, and crimp connectors aren't water-tight. I would use shrink tubing and solder for a project like this. All I needed for this was a heat gun, wire cutters, and stripers. I believe that doing this took me less time than gathering my supplies and heating up my iron would have. There was also little cleanup after I finished.Using them sped up and simplified the process. I can't think of anything bad to say. You don't need to be a rocket scientist to use these, but I highly encourage it.

WGCD 200 PCS Insulated Straight Wire Butt Splice Terminals Electrical Crimp Connector Assortment Kit Review:


These connectors are unquestionably of low quality (you get what you pay for). For low voltage/low amperage connections like vehicle speaker wire and illumination, they are suitable. many connectors for the price. The usage of them for high power would be risky (such as home and industrial electrical work). I'm not sure how well these would endure over time. They are, however, possibly comparable to other inexpensive (manufactured in China? connectors) that you can buy on Amazon and eBay. I was also meant to receive these the following day thanks to Prime. After TWO days, I received them.


How do you remove butt connectors?

Butt connectors are used to join two pieces of wire together. To remove a butt connector, you will need a wire cutter and a pair of needle-nose pliers.
