One for each wire, what is the 3rd?** A: I’m not sure why you have to crimp 3x’s unless their tool is designed that way? I only crimped twice in my engine compartment of my pickup and have had no issues. **Q: Will these work for 10/2 wire at 230V and 20 amps?** A: You should be able to use on 230 volt 20 amp. The yellow should handle 30 amp minimum. Usually if the wires fit in it. It will work **Q: Do you have the Butt connectors that are 12-10 on one end and 16-14 on the other** A: No, they are the same on each end. The colors indicate the size, as well they are labeled. **Q: Can these be submerged? I want to use them for a bilge pump.** A: Yes you can, the discription of the product says they are Marine Grade Waterproof Wire Connectors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 👍 *by S***T on 11 June 2026* Gute Qualität ### ⭐⭐⭐⭐⭐ plutôt pour des gros fils *by J***L on 1 August 2025* Il vaut mieux bien insister pour sertir sinon ça ne tient pas. ### ⭐⭐⭐⭐⭐ good quality good price *by M***L on 3 October 2026* a great set best i have found for the price and it got here on time. great seller this order helped to get my project done in prep for winter ## Frequently Bought Together - 330PCS haisstronica Heat Shrink Butt Connectors-Marine Grade Waterproof Electrical Crimp Wire Connectors Kit-Tinned Red Copper Insulated, for Boat,Truck,Stereo,Joint(4Colors/4Sizes) - haisstronica Crimping Tool For Heat Shrink Connectors-AWG 22-10 Ratchet Wire Terminal Crimper-Ratcheting Crimper Tools-Available For Insulated Nylon Connectors and Electrical Wire Connectors HS-8327 - haisstronica 280PCS Marine Grade Heat Shrink Wire Connectors-Electrical Connectors Kit of Tinned Red Copper,Crimp Insulated Ring Fork Spade Butt Splice(3Colors/21Size) 16-14 22-16 12-10 Gauge --- ## 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.us/products/353304432-haisstronica-330pcs-heat-shrink-butt-connectors-26-10-awg](https://www.desertcart.us/products/353304432-haisstronica-330pcs-heat-shrink-butt-connectors-26-10-awg) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-11*
