They are easy to use, providing a strong and reliable connection with minimal effort. The heat shrink and solder design creates a secure seal that holds up well, even in demanding environments. They’ve saved me time and hassle compared to traditional soldering methods. A great product for DIY electrical projects or professional use. Highly recommended! ### ⭐⭐⭐⭐⭐ Good quality *by M***N on August 2, 2023* I have worked in the automotive industry for over 25 years, installing and ultimately designing aftermarket electrical systems and harnesses. I typically use either 3M or Molex, but these compare and are much less expensive. You could go to your local hardware store and pay 10-20 times what these cost. Very good butt connectors. The barrels are sturdy and the heat shrink is tough. Just use a good crimper and you will see good results. A small, butane torch works best for the heat shrink. Hopefully the quality will continue. Really good buy. ### ⭐⭐⭐⭐⭐ Not bad *by J***R on November 20, 2024* They work and seal pretty well. I have seen no corrosion or wear as of yet. I'll buy again. ## Frequently Bought Together - 340PCS Heat Shrink Butt Connectors, Sopoby Marine Grade Electrical Wire Connectors Kit, Tinned Red Copper Insulated Waterproof Crimp Terminals Butt Splice for Cable,Boat,Wiring - Plustool Crimping Tool for Heat Shrink Connectors AWG22-10, Ratcheting Wire Terminal Crimper - Crimping Pliers - Electrical Crimping Tool - Kuject 320PCS Heat Shrink Wire Connectors Kit, Electrical Waterproof Crimp Butt Terminals, Insulated Spade Connectors for Automotive Marine Boat Truck, Include Rings Forks Spade Butt Splices --- ## 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.pl/products/495475394-340pcs-heat-shrink-butt-connectors](https://www.desertcart.pl/products/495475394-340pcs-heat-shrink-butt-connectors) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
