160 Pcs Copper Ring Terminals, M3/M4/M5/M6/M8/M10 Brass Wire Connectors, Open Barrel Wire Cable Lugs Crimp Kit, Brass Copper Ring Crimp Cable Electrical Terminals Kit

I bought this pack of 100 heat-shrink butt connectors for some wiring projects, and they’ve been spot on. The heat shrink tubing is thick, shrinks evenly, and grips tightly around the wire for a really solid waterproof seal. Once shrunk, the adhesive inside melts perfectly and gives you full confidence the connection won’t pull apart. The metal barrels are decent quality too — they crimp cleanly without deforming or tearing, and they hold the wire firmly. Colour-coded sizing makes it easy to grab the right one quickly, which is great when you’re working on a car, FPV build, or general electrical jobs. I’ve used dozens already and haven’t had a single failure. For the price, getting 100 pieces is great value, and the quality is better than a lot of the cheaper connector kits I’ve tried before. If you need reliable, weather-resistant connections, these heat-shrink butt connectors do the job perfectly. Highly recommended!

Great quality and loads of different sizes to choose from

They do the job, not overly expensive.

Good selection of sizes and they crimp nicely. Useful to have in the toolbox for quick wiring jobs.

All good

Not very good quality. The wire kept coming out of the connector.

Good kit

Not the strongest of connectors. I always solder wire to this type of terminal and then use heat shrink of appropriate colour to insulate , which makes a reliable bond.
