Recommended by mechanics and DIY ENTHUSIAST

Great product, this is what I needed my whole life. Great secure connections made if this product is used correctly. Just follow the directions and you can't go wrong!

These are amazing! They solder, bind together, and weather-proof! I wish I would have known about these 20 years ago!!! They make wiring projects in the car, boat, and RV a snap. I use them for mostly 12V projects.

I just finished rewiring my utility trailer with these. So easy and gratifying. I've always hated crimp type butt connectors, so I would always solder my connections and cover them with heat shrink, tedious and time consuming. These take the trouble out of all that.

Easy Identification

Color-coded tubing makes it easy to identify the right size connector for every application. Measure your wire, and easily choose the right connector by looking at the wire size chart on the box.
