[volt-nuts] 7081 connector part number Q

The mickle way seems the best, but I have to find some
solid teflon, and a way to drill precisely.

I could also put a good quantity of teflon tape around
the pins, so the resin doesn't come in contact with the
measurement pins, but after I should test the connector.
Is there a way to estimate the leackage for such a cable?
