The crimps you see on submersible well conductors would be fine. It is
an irreversible crimp with silicone in the shrink tube insulation. The
problem is you need the right tool to make the crimp and the one for
6ga wire is probably $100. I did see a guy who went to work on a 36"
Harbor Fright bolt cutter with a grinder to make a big crimper. It
seemed to work OK.

A related sidebar Q? --

Is there anything/any way to repair knicked insulation on an underground
feeder?Â* Or just go ahead and cut to use the splice kit?

I managed to cut insulation on one side of feed to house during the work
around the old foundation when discovered the conduit out bottom of
outside junction box wasn't nearly as deep as had presumed Dad would
have left it...and, unusual for him, there was virtually no slack in
that line to be able to really do a good job wrapping it (...both of
which make me think he must have sublet that work instead of having done
himself--just not characteristic of something he would have done on own.
Â*He worked on remodel/refurbish of grandparents house for 5-6 years and
had to take off for real job of farming for extended periods during
summers so let out some of the work).

I sorta' cobbled a tape job w/ some of the cold-vulcanizing tape
followed up w/ electrical tape and then covered that with a good coating
of one of the liquid rubber products as water seal -- then covered it
after dried w/ another tape wrap.Â* We'll see how long it holds...

Was more than unhappy when discovered what had done...

Would something like this have worked? Put the actual splice away
for someday and use the insulation.
