ANVINKU 150pcs Solder Seal Wire Connectors, Heat Shrink Connectors, 4 Types Waterproof Solder Joints Heat Shrink for Marine Vehicle Electrical Engineering

Used on a few projects on my car. Saves so much time and provides confidence that soldered connectors are waterproof

I have always been rubbish at soldering and its part of the reason I always opt for crimps when carrying out wiring on cars. I saw a few reviews and videos of these online and figured I would give them a try.I have to say im very impressed. I used them on small gauge wiring. I have a non branded heat gun that uses LXT batteries and this works great on these soldered wire connectors as it gets hot enough to melt the solder but it doesn't damage the insulation. When finished it gives a nice clean, strong water proof joint. The hardest part of the job is twisting the wires together, especially if they are small. I did see a video that suggested its worth dipping the wire ends in abit of flux to help the solder flow better which seemed to do the job for me. Probably not as good as soldering by hand but aslong as you arent sticking loads of current through these they will do the job fine.

Very pleased with the purchase

Brought these as an alternative to soldering. Easy to use and the connection seems solid enough. Time will tell but no complaints so far.

They work but the joined from the solder is not graye most of them I used I could them.pull the wires apart use these aloy in work found there to be sub par

Just the job

Used to hardwire a connection on my motorcycle loom, very easy to use and connection has held up so far, good product! Take care when applying heat to melt the solder so as not to damage the wires insulation!

Awesome, easy to use
