Wirefy 50 PCS Heat Shrink Butt Connectors Yellow 8 AWG - Larger Diameter Marine Grade Butt Connectors - Wire Butt Splice Connectors - Electrical Waterproof Heat Shrink Butts

This kit pretty much includes any size I would need and comes in a case that seems somewhat sturdier than others. I have used a couple sizes from the kit on a small cargo carrier project I did. Each tube used crimped great (using their tool), shrunk perfectly, and seems pretty weather tight. All that is well and good, but the key is that each electrical connection worked flawlessly. This kit may cost you fractions of a penny more per connector, but you are paying for quality in each one. To me that is well worth a couple dollars more. I would recommend this kit and the crimping tool they make as great companions. The company just needs to put both of these into a nice convenient kit with a space in the box for the crimping tool.

Good quality

I’ve been using these connectors in a damp marine environment, and they’ve held up just as well as some of the higher-priced options I’ve tried. They crimp cleanly, the heat shrink tubing seals tightly, and I haven’t had any issues with moisture intrusion. I appreciate that each connection feels secure once heated, giving me confidence in long-term durability. For the price, the performance is excellent, and they’ve become my go-to choice for boat wiring projects. . What you may care about: • Seal quality (Meets) • Durability in damp environments (Meets) • Value for the price (Meets) • Ease of installation (Meets)

I have used similar connectors which shrink to seal the wires and ideally also cause a soldered connection, but the insulation around the soldered union tends to break down somewhat thus rendering the end result unacceptable. However, this design is substantially more robust both on the crimped/soldered union and for the shrink plastic. The only complaint is that what's supposed to end up as a soldered connection doesn't appear to be complete. Still, the resulting union is strong, intact and waterproof.

I used these when splicing in my graphs and speaker system. They appear to be well made and do what I wanted. They hold well even with all the vibration of going across the water.

Best wire crimps

They work! Much better than most.

Must crimp first. Thought the metal was to melt first

I migliori in assoluto uguali come qualità a quelli cembre ma con un costo veramente ridotto già usati 600 perfetti
