keep water out.

Well, I did that and it kept the interior almost dry - but the
silicone acts like an adhesive and makes the "wedged" wire really
really hard to get out of the wedge shaped cavity in the body.

So, I wondering about some long-term sealer-filler that not an
adhesive. I've gotten 8 of 8 apart so far, but don't want to go thru
this again.

Maybe Dolfinite (it shrinks). Ideally something that expands when it
cures, is rubbery, not UV bothered, and zero adhesion to s/s.

Suggestions?

I doubt that the problem is primarily due to the sealant you used when
assembling the fittings as I have disassemble a number of fittings
installed without no sealant and they were extremely difficult to
disassemble. When finally taken apart I found that there had been so
much force applied as to cause the wires to indented the wedge.

To disassemble cut the cable flush with the fitting using a 4 inch
hand grinder; remove the threaded outer sleeve and supporting the
sleeve drive the cable and wedge out using a punch having a diameter
nearly that of the wire and a heavy hammer. Replace the wedge and
reuse.

Close, but no cigar! What's with the 4" hand grinder when a simple hacksaw
works just fine?

But, you ARE right (this is the second or third time) about the force being
applied to the cone. That's the patented secret of a Sta-Lok mechanical
terminal. It gets its strength from both the cone compressing upon and
gripping the "1" part of the 1X19 while it bends the ends of the "19" over
the nut and compresses them at about a 30 degree angle on the same taper in
the body of the terminal. The sealant is only used to keep salt water out of
the inside of the terminal where it will fester and cause corrosion,
electrolysis and other problems.

Stop me if I'm wrong, but I don't think there's a "1" part and a "19"
part; there are 19 different "1" parts. And the cone actually goes on 7
of those "1" parts, with 12 more on the outside.

Stop! You are wrong. The nomenclature of wire such as 1X19 means the
following: The first is the number of strands and the second number is the
number of wires in each strand. So, 1X19 is one strand made up of 19 wires.
Modern 1X19 does, indeed, have a core of sorts consisting of seven wires
around which the other 12 are twisted. This core is the part around which
the cone is compressed.

The purist might say a 1X19 is not a wire rope at all for it consists of
only one strand made up of 19 thick wires but it is generally called a wire
rope.
