Fast, easy and safe method of splicing all types of wireing. - Great quality and nice variety of sizes. I bought these to have them on hand for when I need them which when you are living and travelling full time in a 5th wheel is pretty much anytime something stops working it seems everything is somehow tied to electrical in one of these and because it's like a earthquake in the trailer every time you move it things break and come loose fairly often. I've used several of these already and love having them onboard because every time I've used one the outcome has been perfect the melt exactly like they should using my 1500 watt hot air gun all you have to do is strip and short piece of each wire end your using first insert one wire end into the splice and melt the splice onto the wire, insert the other wire end into the open end of the splice and again melt the splice with a hot air gun or other heat source the metal center of the splice will complete the circuit making the wire whole again that's it it's not hard at all. I've had great success with these in the trailer and in my pickup I use to tow the 5th wheel I don't see running out of these anytime soon but when and if I do I will be buying more just like these from this seller.

I have already bought more to refill the more common sizes. ### ⭐⭐⭐⭐ Great product with a little learning curve *by J***Y on October 25, 2019* It was my first time using these and overall they're a great product. The included sizes worked great for my car audio application where I was connecting 2-3 22-18ga wires. I used my Wagner heat gun to shrink and solder, which worked well overall. There was a bit of a learning curve, some tips or instructions would have been welcome. The biggest issue I had was the solder would take long enough to melt that the heat shrink would start to melt thru a bit exposing some of the wire connection. Not enough to matter for my application, however. I found that I had to frequently rotate the piece as I heated it to prevent the melt thru. Other than that, great product and will now be my go to for any wire connection. ## 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.hr/products/146764547-200pcs-solder-seal-wire-connectors-sopoby-waterproof-solder-butt-connectors](https://www.desertcart.hr/products/146764547-200pcs-solder-seal-wire-connectors-sopoby-waterproof-solder-butt-connectors) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-25*
