Is it possible in the UK to buy just one or two rolls of heat
shrink TAPE? I mean something similar to regular self-adhesive
PVC insulation tape but which contracts when heated. Does such a
thing exist?

My web searches such as this one at Farnell's
http://snipurl.com/skla return heat shrink SLEEVES which is not
what I want.

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..).

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


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.

Just what I want.


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.


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.
