grannyknot Posted August 4, 2018 Share #1 Posted August 4, 2018 Just came across this product that looks like it might be useful, I haven't tried it yet but it looks promising. https://chicdelta.com/products/waterproof-solder-wire-connectors?variant=9024946831407 Link to comment Share on other sites More sharing options...

Zed Head Posted August 5, 2018 Share #3 Posted August 5, 2018 I used shrink tubing with adhesive for some over the engine wires and the hot melt melted out of the tubes and dripped on to the heat shield under the intake manifold. Maybe do some testing before going crazy. Choose the usage environment carefully. Does look interesting. Link to comment Share on other sites More sharing options...
zKars Posted August 5, 2018 Share #4 Posted August 5, 2018 I've seen these all over FB lately. I'm skep-tickle that the low temp 'solder' bonds to the wire the same way that regular solder does. And it would be subject to failure in high temp under hood conditions as ZED Head warns. It's the "Adgesive" that I'm really worried about..... 1 Link to comment Share on other sites More sharing options...
Patcon Posted August 5, 2018 Share #5 Posted August 5, 2018 I don't know about using those on a car but they would be perfect on my invisible fence... Link to comment Share on other sites More sharing options...
grannyknot Posted August 5, 2018 Author Share #6 Posted August 5, 2018 All good points, I just ordered the 50 pk and I'll do some testing on the hot side of the engine and post them here. Link to comment Share on other sites More sharing options...
240260280 Posted August 5, 2018 Share #7 Posted August 5, 2018 These work great for 22awg water proof connections. The good ones have silicon gel in them: I used to make circuit boards using surface mount technology and solder paste was used. It was deposited with a syringe. A high temperature vapour was used to melt and flow the solder. Link to comment Share on other sites More sharing options...
grannyknot Posted October 5, 2018 Author Share #8 Posted October 5, 2018 So I paid for these connectors Aug.5th, just got them yesterday Oct 4th. They forgot to mention on their site that your package is drop shipped from China, I don't mind waiting if I know about the wait time. I assumed a couple of weeks, so I started emailing them, all you get is one of three different form replies apologizing and asking for more time. Very frustrating, however the product is very good. Some 14 ga and 12 ga for the test pieces, using my paint striping hot air gun on Max which is about 800* F After cooling I mounted them one at a time in the vise an pulled with a pair of ViseGrips, I really had to put my weight into them to get them to break, very good bond, It is the solder that breaks, I could have held the heat to the 12 ga wire longer and got better penetration of the solder. 50 connectors for $23 usd and 8 wks, not too bad, 4 Link to comment Share on other sites More sharing options...
wheee! Posted October 6, 2018 Share #9 Posted October 6, 2018 I am a little old fashioned I guess. I still prefer a “western union” with a solder bond and heat shrink tubing. This style does provide a slim finish though. Looks like the wire tore before the solder joint so that’s good. Link to comment Share on other sites More sharing options...

I still prefer a “western union” with a solder bond and heat shrink tubing. This style does provide a slim finish though. Looks like the wire tore before the solder joint so that’s good. I prefer the old way as well but I can see these coming in handy in those situations where there is limited access and you need 3 hands to juggle the wire, solder and torch or soldering gun. I forgot to mention I did an Ohms test because I thought there might be some resistance with that low heat solder but there was none. It is actually the solder that breaks the most with a few strands of the other wire tearing away, it was difficult to get a good pic as I was shooting through a magnifying glass. But as I mentioned I had to really haul on it to get it to snap, I guess low heat solder would have more lead in it. I might try dipping the ends of heavy ga wire in flux next time so I get better penetration to the center of the joint. Link to comment Share on other sites More sharing options...
Namerow Posted October 6, 2018 Share #11 Posted October 6, 2018 Looks like a great solution to a longstanding repair/restoration issue. Good to have your 'lab test' results, verifying the mechanical strength and electrical quality of the resulting connection. I'm always a bit unhappy with my Western Union-style connections because they're so bulky. Good mechanics, bad aesthetics. These look much more acceptable than the ubiquitous crimp-on connectors that are typically used to fix cut or broken wiring. And a lot better than solder-and-electrical tape! Hard to believe that underhood temps would ever get to the level of melting the solder here -- unless the connection is sitting near the exhaust manifold. 1 Link to comment Share on other sites More sharing options...
