100 PCS Heat Shrink Butt Connectors | 16-14 AWG Solder Seal Wire Connectors | Waterproof Crimp Terminals For Marine, Auto, DIY

Need a strong, waterproof way to splice two wires together? These solder seal butt connectors are awesome. You get 100 pieces in the pack. They're sized for 16 to 14 AWG wire (or 1.5 to 2.5 mm²). Each connector has a pre-loaded ring of solder inside and a heat-shrink tube around it. Here's how it works: you strip your wires, twist them together, slide them into the connector, and then hit it with a heat gun. The tube shrinks to form a waterproof seal, and the solder melts to create a solid electrical connection. It's way more reliable than just twisting and taping. Perfect for automotive wiring, boat electronics (marine grade!), outdoor lighting, or any DIY electrical project where moisture might be a problem. They're clear, so you can see the connection inside. Just make sure you pick the right size for your wires!
