Well, we KISS and make up.

Then you can judge the situation and decide what level of risk. In certain situations not even Teflon is satisfactory.

This is the highest level we have ever seen on=2 0any component we have used of any type. I didn't think that a connector could be moisture sensitive. Not heat tolerant, yes - we have melted a few - but moisture sensitive? What kind of damage can happen to a nylon connector from too much moisture absorption? Thanks in advance for your responses.
