The only connector they claim is water tight is the Posi-Tite in line connector. The Posi-Tap would be the connector that would work for my application.
Posi-Tap- No Crimp Tap
.While they recommend some of the other connectors for outdoor lighting and marine use, it's not mentioned for the Posi-Tap. Guess I could seal it with liquid electrical tape, but it would make a mess of what was a elegant solution. Interestingly, they claim their Posi Twist connectors eliminate 80% of the resistance of crimp-on connectors. If accurate, thats a lot! But then...maybe you could say the same about regular twist locks, as the wires touch in the same manner.
Looks like you can only get them from Crutchfields. Has anybody used the connectors? What about the resistance claim?
