I've finally exhausted the majority of the 50 pack and just gladly ordered the 280 and can say that 20-25 for these things is a great deal for how effective these are. For super permanent or less space-starved fixes I still prefer to sit down and solder/wrap normally (like wiring a car stereo) but for just about anything else, even stuff you might come back to, these are a game-changer. You can hold more heat shrink onto the back of the wires since it takes way less heat through the wire to secure these than actual solder where the wire itself can get pretty hot, especially larger more conductive wires that might start closing the heat shrink down the wire prematurely while securing the joint. This actually saved my butt when my headlight wire got caught leaving work (I get off after dark). I had thrown a few in my backpack "just in case" and it actually came up. These are super convenient and get the job done. They're actually pretty solid, too, and feel relatively trustworthy. I like these better than the hard, plastic crimps that don't shrink down, obv, but I mean these things are definitely more solid, and I feel like I've gotten those things tight. For anything worth anything that needs to be permanent, you want to splice, solder, and heat shrink. But when that isn't an option anytime soon, these are by far the most clutch tool to have in your electrical toolbox. Review: Not sure how I made it all these years without these! Make wiring more doable. - I love these things! They are one of those things that Idk how I made it without them. I seen someone use them on a car show or YouTube and figured I’d try them. So glad I did because they make wiring a bit easier. All you do is strip the wires and slide this these over them. Then take a heat gun or lighter to heat it up. This melts the solder so it goes over the wires making them water tight and giving it a great connection. Plus the rubber/plastic keeps water out while the solder gives it a great connection. Take my word for it and BUY these! If you do any automotive wiring you will love these. A lot of people don’t solder because it takes time to setup everything ,which I felt the same way before these. These solves those issues and gives you a better stronger bite since they are soldered. You will love these things I guarantee you. I’ve been using these for over a year so I know 1st hand that they last and I know how well they work. I use a lot of the blue ones while wiring which wiring isn’t my favorite thing to do ## Features - PREMIUM SOLDER SEAL RING: Tubing reduces in size, the enough solder will melt and flow through the stripped wires, ensure a long lasting connection for your application - BETTER WATERPROOF SOLUTIONS: Double wall design, Hot Melt Adhesive inside ensures wires strongly connected and prevent wires slipping from the terminal; Polyolefin outside tubing provides insulation and improves pullout strength - ABRASION RESISTANCE HEAT SHRINKABLE TUBE: Premium tube materials are specially designed to be used in harsh environments. Protect the wires and cables from abrasion, cutting, scuffing and low impact situations - EXCELLENT WIRE CONTACT - The tin barrel provides increased current flow, and ensures less voltage drop, preventing wiring failures and reducing equipment downtime - WIDE APPLICATIONS: Excellent stability, water resistance and electrical conductivity provide durable connection for motorcycle, off-road vehicles, lawn tractors, RVs, fish finder and marine application. Widely used on multiple projects of your Christmas lights, ships with high waterproof requirements motorcycle stereo, boat electronics, equipment switches ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R4Z13P3 | | Best Sellers Rank | #18,960 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #117 in Butt Terminals #12,351 in Electrical Equipment | | Brand Name | Sopoby | | Color | 10 Yellow, 70 Blue, 70 Red, 50 White | | Connector Gender | Male | | Connector Type | Solder | | Contact Material | Copper | | Customer Reviews | 4.6 out of 5 stars 8,254 Reviews | | Gauge | 10 | | Insulation Material | Polyolefin | | Insulation Material Type | Polyolefin | | Item Highlight | Heat Shrink Insulated Automotive Electrical Wire Terminals for Marine Automotive Boat Truck | | Manufacturer | Sopoby | | Material | Polyolefin Tubing with Hot Melt Adhesive & Solder inside | | Material Type | Polyolefin Tubing with Hot Melt Adhesive & Solder inside | | Maximum Voltage | 12 volts_of_direct_current | | Model | Sopoby-XXX | | Number of Items | 200 | | Number of Packs | 1 | | Part Number | Sopoby333 | | Specification Met | ① Minimum Shrink Temperature: 80℃, ② Minimum Temperature for Solder to Melt: 138℃ | | Stud Size | 10 gauge or 3.2 mm | | Temperature Rating | Working Temp: -67℉ - 257℉ | | Terminal | Butt Terminal | | Unit Count | 200 Count | | Wire Diameter | 6 millimeters | ## Product Details - **Color:** 10 Yellow, 70 Blue, 70 Red, 50 White - **Connector Type:** Solder - **Contact Material:** Copper - **Insulation Material:** Polyolefin - **Terminal:** Butt Terminal ## Images ![200PCS Solder Seal Wire Connectors, Waterproof Solder Butt Connectors Kit - Image 1](https://m.media-amazon.com/images/I/71mFM7KwgvL.jpg) ![200PCS Solder Seal Wire Connectors, Waterproof Solder Butt Connectors Kit - Image 2](https://m.media-amazon.com/images/I/714DcYpORmL.jpg) ![200PCS Solder Seal Wire Connectors, Waterproof Solder Butt Connectors Kit - Image 3](https://m.media-amazon.com/images/I/71GIoOMvWkL.jpg) ![200PCS Solder Seal Wire Connectors, Waterproof Solder Butt Connectors Kit - Image 4](https://m.media-amazon.com/images/I/71S1pw-7+CL.jpg) ![200PCS Solder Seal Wire Connectors, Waterproof Solder Butt Connectors Kit - Image 5](https://m.media-amazon.com/images/I/71HrBwG0fjL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SUPER Convenient to use for quick in-field repairs *by S***E on February 29, 2020* *EDIT 5/1/2020* So I'm positive these are the best things in the world.

I use a lot of the blue ones while wiring which wiring isn’t my favorite thing to do ### ⭐⭐⭐⭐ Works but... *by B***N on August 18, 2021* As an Engineer I found this to be a great idea so I tested it out on a piece of wire which I stripped and twisted together. I slid one of the red shrink sleeves over the joint then used a lighter, and after a few seconds of moving the flame back and forth, the solder seemed to melt and it looked to be a good connection. Then I tried pulling it apart and the connection failed. I then tried again, but this time I dipped the stripped ends of the wire in Flux which is a very necessary part of the soldering process. Not only did the joint work perfectly after using the flux, it also heated up much faster, reducing the chance of melting the plastic. Without the flux you can get what is called a "cold" joint where the solder melts but doesn't really flow onto the wire. I don't know if the average person has flux laying around but it would be great if they included a small tube in the kit. Or better yet, figure out a way to line the inner part of the shrink tube on either side of the solder, so it gets applied to the wire when things heat up. Great idea and works in a pinch when you don't have electricity for a soldering iron - just needs flux! ## Frequently Bought Together - 200PCS Solder Seal Wire Connectors - Sopoby Heat Shrink Solder Butt Connectors - Waterproof Solder Connector Kit Insulated Automotive Electrical Wire Terminals - ASHINER Heat Shrink Tubing Kit - 580Pcs EVA Material in 6 Colors and 11 Sizes - Ideal for Electrical Insulation, Repairs, and Wire Connectors with User-Friendly Design and Storage Case - SEEKONE Mini Heat Gun 2 Temperature 260℃/450℃, 350W Handheld Hot Air Gun Tool 1.5S Fast Heating with Overload Protection, Non-Slip Rubber Body, Nozzle for Craft Embossing, Shrink Wrapping --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/146764547-200pcs-solder-seal-wire-connectors-waterproof-solder-butt-connectors-kit](https://www.desertcart.gr/products/146764547-200pcs-solder-seal-wire-connectors-waterproof-solder-butt-connectors-kit) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-11-03*
