I wish I had found these from the start! It would have saved be a lot of time having to reapply the non- heatshrink ones. Well worth the money! You will definitely need a heat gun to seal them properly ### ⭐⭐⭐⭐ Best Quality *by R***S on 13 May 2021* More solder than some of the cheaper versions ### ⭐⭐⭐⭐⭐ As good as expensive brands *by R***S on 10 December 2023* I have long been a Fan of Wirfy but getting their crimps is expensive. I needed a bunch of these smaller crimps so at about half the price took the risk. I can confirm they appear to work in exactly the same way and are as easy to use. They do seem a bit smellier when heating. Would recommend. ## Frequently Bought Together - Yosawo 100-Pieces Heat Shrink Butt Connectors,Waterproof Insulated Wire Connectors,Marine Automotive Crimp Terminal Connector,Hot Melt Adhesive Butt Splice DIY Kit 16-22 AWG Red - 150 Pieces Heat Shrink Butt Connectors Kit, 22-16 AWG Red Insulated Waterproof Electrical Wire Connectors Automotive Wire Crimp Terminals Butt Splices - 100 PCS Solder Seal Wire Connectors Heat Shrink Solder Butt Connectors Waterproof Insulated Electrical Butt Splice Wire Terminals, White 26-24 AWG --- ## 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/133763181-50-pieces-professional-heat-shrink-butt-connectors-crimp-connectors-waterproof](https://www.desertcart.hr/products/133763181-50-pieces-professional-heat-shrink-butt-connectors-crimp-connectors-waterproof) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-10*
