Solder Heat Shrink Splice?

Anybody use these? Pro's Con's? They look pretty handy, just looking for some real world input on their performance. Thanks!

 

I managed a road department for 34 years. My mechanics used them a lot with heavy machinery and big truck repairs. Never had a single problem with them. Be sure you have a good twist on the wire ends.

Thanks SPark!

 

wow.. nice! I've never seen those before. What exactly are they called(brand?) and where to get them?

 

I have never used that brand, those are nice and clean looking.

I have used hundreds of the harbor freight ones, and never had any issues with them. Used them to wire up a golf cart, and also when I redid my engine bay harness.

 

The brand for the picture is http://www.calcentron.com/Pages/fusion_solder_heat_shrink/fusion_solder_heat_shrink.html

I had never seen them either and was looking for clean solution for a little wiring project I'm doing. It seems you just use a standard heat gun +500deg. and presto clean soldered splice wrapped in heat shrink. I'm going to order some tonight, easy to find on ebay or amazon etc...

 

I also saw them here, apparently they are popular with the aviation crowd!


I figure if it’s good for fliers, it’ll be overkill for my Maverick. Just the way I like it!

 

ordering a crap load of those today...

 

I did electrical installation work, building trucks for Altec Industries, back around 2000 and some customers demanded this style of electrical connections - granted ours were different looking (believe they were made by AMP) but worked the same way - one word of caution is, when you are using a heat gun, as soon as the solder turns to a liquid, pull the gun back or the solder will shoot out of the end of the connector - I did a lot of trucks for Rochester Gas & Electric and only remember 1 spice fail

 

Do you need a torch, or will a heat gun work with them?

 

I used a Milwaukee heat gun

 

I don't like them. We use dozens of them every day at work, Tyco Raychem (used to be Amp). Problem is that small ring of solder in the center often isn't enough to provide a good, solid, penetrating joint and you have more control of the soldering process using an iron. We often have to pre-tin the wires and then apply the solder sleeve. To me, if you're pre-tinining the wires you might just as well solder them together and cover with regular heat shrink. But that's what some of the customers want on their products.
