HKS 200 PCS Solder Seal Wire Connectors - Red 22-18 AWG - Heat Shrink Solder Butt Connectors - Automotive Marine Boat Crimp - Waterproof and Insulated

Works great

These are the perfect connectors for small wires. Their small size and streamlined construction makes for a clean and neat install.

These things were great. I use them because it solders the Wire and keeps water out the best way to buy. These are in bulk to save money. Blue is the one you will need the most a little truck I found when you put the Warriors and take a pair of pliers and squeeze the Sauter and it’ll hold wires together for you.

Modern day cars of the last I guess 20 years just the right size for most wiring on automobiles today I'm very pleased I'm a backyard mechanic and I rewire cars all the time install extra lights on my pickup trucks my trailers my cars and use these combination heat shrink solder joint and waterproofing glue combinations a couple times a week. Recommend, yes.

These are definitely an excellent value, but their usefulness to you will depend on your use case. All types of low temperature solder are inherently somewhat brittle. If they are subjected to serious vibration or mechanical shock, the joint will more easily crack than will a joint with regular solder. The other issue with these is getting the solder to flow. You will mostly fix that issue by dipping the tips of your wires in flux before inserting them in this connector, and applying more heat to the joint than you normally would to shrink the tubing.Overall if you need a quick and easy joint that will not be subject to unusual stress or vibration, you will probably be happy with these. If you need a bomb proof connection, then crimping with a proper crimp tool followed by application of heat shrink tubing with adhesive inside is truly unmatched.

I have so many of the older versions of the heat shrink connectors stopped using them these are the only ones I use and a lot of my associates are using them as well

Works Great!

These things are the best wire connectors since they invented the wheel! LOL maybe even better that the wheel. I know no relation but the wheel was a great invention. So is this.Put your wire ends in heat it up and your done. No worry they will pull apart since they are soldered, get wet the silicon heat shrink seals it.Heat it once it's done. No crimping!
