I've never seen or heard of such a product. Perhaps self-amalgamating tape
will do what you want?

You can get high shrink ratio sleeving - I think RS do it - this has something like a 3 or 4:1
shrink ratio

I am the OP. The only time I used self-amalgamating tape it was a
squishy thing when it was finished. I would much rather have
something "drier" and less sticky as a final finish.

I doubt it as the principle is flawed.

Have you tried the type of heat shrink with the glue inside? That's what I
use for the more demanding apps.

Self amalgamating tape isn't sticky. But it's not really a substitute for
heat shrink.

Glue-lined zipper heatshrink tubing. You open up the tubing, lay in the
cables, zip the tubing shut and apply heat. Aftrwards, cut off the
zipper along its length with a craft knife, to leave a round cable.
Handy for all those time when you can't get a tube over the end
(especially in the middle of a cable run, replacing a section of damaged
cable..).

The result is a totally water and air-tight cable assembly - as the glue
exudes out of the ends of the tube to make a perfect seal.

But rather over-kill for inside a PC. Spiral wrap is cheaper and more
flexible - as it allows all the cables to be wrapped together, with
cables exiting from the spiral wrap at intermediate points. It comes in
a range or diameters.

"Zip the tubing shut"? This sounds clever. Do you have a link to
where this product is shown?

It's not inside a PC but outside. For example, I have a mic cable
which plugs into the PC. It has a joint which I have made and the
cable gets moved a lot. Most of the PVC insulating tape I have seen
starts to open up or even unravel under the repeated flexing. So I
want to seal the insulating tape on the joint or to replace it
entirely with something which canbe sealed and not need any further
attention.

Just search for "zipper heat shrink tubing". I buy mine from my local
electrical supplies company. It is used a lot to make permanent repairs
to mid-sections of power cables.

Zipper tubing is *very* inflexible once set. Fine for inline repairs to
cables that will not normally move but not for anything that you want to
flex.

As others have said, self-amalgamating tape sounds like the answer. It
will *not* unravel - as the stuff bonds to itself to make a solid
covering. It will not open up.

If you cover the joint in hot-melt glue and, before the glue has
hardened, wrap the joint with self-amalgamating tape, the result is
almost as good as zipper tube. It can't be used for mains as the
insulation thickness is uncertain (unlike zipper tube, which can be used
for mains voltages and above). Be careful not to burn your fingers...

Best thing is not to have a joint in a flexible cable. A suitable
connector would be a better solution. The snag with heatshrink for this
use is it's not flexible - so the cable flexes immediately before or after
it and breaks. A proper connector will have a rubber gland which sort of
spreads the length of the cable flexing.

The normal mic connector is of course the XLR - but this might be a bit
big and heavy for this use - especially if the PC connector is the
standard mini jack. If the mic and cable is getting a lot of movement, I'd
fit an XLR chassis connector into a suitable instument box and weight or
fix that down and run a cable from there to the PC - and plug the mic
cable into the box. An XLR mic cable is designed to be flexed without
damage.

Simple lateral solution: Make a loop in the cable with the joint at its
centre...

There are at least two shrink capacities in shrink wrap. You must have
come across the version that shrinks (I'm out on a limb here, as I was
not the user of this stuff) by so many percent and there was another
that shrank twice as much. I can't give you any further info, other than
it was used in the aerospace industry.
