This is the waqy to go on butt connectors and end

Low temp soldering with waterproof connections you solder with a heat gun, 'How sweet it is!!'

Nice. Thanks for the tip!

I think I'm going to switch to them from the crimp on type.

Thanks, I've never been able to make crimp connections work on a consistent basis. This looks like the way to go for me. Where's the best place to get them, or does everyone carry them.

Ebay I would say, but I don't know who carry's them in each part of the country.

It never ceases to amaze me, but once again Amazon has several types available. Here's one: http://www.amazon.com/3M-Heat-Shrink...cal+connectors

OK Ozz, just how much is the heat gun that you need for these connectors and splicers?

Here is an inexpensive set:

Rondo buddy! A guy should have a heat gun anyhoo.. but, $11, 30, 62, from cheap to not-so-much-cheap.

Don't confuse heat shrink with sealed solder, not same.

heat shrinks and is a sealed solder connector, I imagine each manufacturer calls their different products a different name.
The sealed solder and a heat shrink end are similar to the examples I posted, but not the same, as you, wise sir are stating.

Thanks Ozz! I do have a heat gun but not one that has that special end on it to reflect the heat. Mine is a regular heat gun like the DW's hair dryer! Guess I could use it but the smaller one in your posted site is a nice unit and looks a lot more handy than the big bulky one I have! Maybe Santa will bring me one! Have a Merry Christmas!

I've been using the crimp type heat shrink connectors for years and haven't had a problem. But this is definitely an improvement!

Since the solder ring melts at such a low temp, what happens when a heavy amp load is demanded and the solder re-melts?

I think I'll stick to crimp terminals and crimp with my hydraulic crimp tool, and regular solder and iron for jobs that need to be soldered.

If the circuit gets that hot, the solder joint is the least of your worries.

Yep on the melting solder, a wire that gets that hot.. is an electric heater. The connection would be find for any wire repair

Hi Ozz

I have used those on some of the equipment I “play” with. The solder is very low temp and you make the connection with a heat gun that delivers air at a temperature that doesn’t burn your hands unless you hold the gun on your hand for a greater period of time than you would a soldering iron.

We use them only on the wires for sensors like throttle position and mass air flow sensors that are low amp connections.

Crimp on type “environmental” connectors is water resistant and work very well.

I have worked with all types of electrical connections for the past 35 years. Everything from 150KV down to millivolts and microvolts. High current thousands of amps to microamps in various applications and I have seen my share of "Don't do this dot com".

I do not understand how these connectors can provide a reliable low current junction. This low melting temperature (solder?) is just acting as a filler impregnated with something conductive.

You can even purchase conductive epoxy that would not require a heat gun at all. Have I used it? absolutely however, I understood the application and why it was necessary.

If the termination being made is not in the milli ohm range then you are potentially adding a resistor to the circuit dependent upon the quality of the electrical bond. A bad crimp, a cold solder joint, or bad mechanical lug or splice would have the same effect

This could create a fire hazzard if not fused properly. Even if the circuit only drew 1 amp of current it could catch fire at that junction point due to overheating if a load shorted to ground or another potential.

The only time I would trust this type of electrical connection is with a milli amp or milli volt circuit. Similar to the thermostat for the heat or air conditioner or the gas pilot millivolt generator.

Have a safe New Year and a Merry Christmas.

Are you amazed that Amazon has them or that they are made in the US?
