How to make a waterproof wire splice?

Jeez...

@Clexxy,

I have some of the splices that I liked to over 18 years old under my 4x4, and after all those years of salt, snow, rain, mud, etc. they are still holding up.

Just sayin'...

Just sayin, a crimp VS solder connector strength and transmission are far different. I work with 5V CAN systems, and the only splice approved for use is the one I listed, it will stand up to mechanical stress, water, chemicals, and transmit voltage and signals more reliably than any crimp connector made, the only alternative is to install a Deutsch connector with the approved radial crimp tool http://www.amazon.com/dp/B0075P88IY/?tag=tec06d-20 for the pins http://www.newark.com/deutsch/0462-203-12141/crimp-contact-socket-12-14awg/dp/91R1818?mckv=sDgDIZ7EE|pcrid|57087226941|plid|&CMP=KNC-GPLA https://laddinc.com/

OK, Steevo, I am not going to argue with you, but having been in the electrical trades for more than 30 years, I have found those crimp-only splices to be more than adequate for the overwhelming majority of low voltage single stranded copper conductor connections, if properly applied.

A properly crimped connector; by which I mean the connector is properly sized for the conductor, the correct stripping procedure is used, and the correct termination tool is utilized to apply the terminal within the specified range, will exhibit the same electrical characteristics, resistance and conductivity, as an unbroken conductor.

As the OP was wanting to make connections to a 12V waterpump, I believe the splices I recommended were more than adequate.

Also, while not exactly pertinent to the conversation, the NEC forbids connections that are based entirely on solder, instead requiring some form of mechanical attachment.

So not a 20 ga wire in a red scotchlok?

I get it, and for anything that is requiring exact voltage tolerances crimp type are good enough, but I am retentive about my wiring as all I work with is high speed CAN, long distance serial, 1W of 900Mhz, and all this is on some of the worst conditions in the world so anything that offers a failure point in conductivity, a change of more than .187 Ohms at 2.3-2.7 VDC is considered a failure point.

And yeah, the thread is old, but..... its still a good reminder about how to properly wire things, no duct tape on bare twisted wires, no electrical tape on frayed wires, no liquid tape to act as a potting material.
