I need to get 5 cables down a 8" lengh of plastic ducting (which is already
embedded through a wall) - 3 TV/coax and 2 ethernet cables. I've slightly
miscalculated, and it's going to be a very tight fit - but I'm sure they'll
go. Four are already through OK, it's just the last one which is proving
troublesome.

I'm minded to try lubricating them... what would be a good choice in terms
of efficiency and cable longevity, bearing in mind they will be in place
'for ever' and will be tightly squeezed together?

And no, making a bigger hole is no longer an option now, OK?!!

Thanks

Here you go:

In the old days, they used tallow - but not with PVC and it would
probably get a bit rancid after a while...

I've used a drop of talc before - that can be just enough if the cables
are binding a bit and it's dry and unmessy (well hoovers up easily)

Pull out what's already through, bind the ends tightly together,
possibly slightly staggered to make a bit of tapered lead in and pull
all through as a single unit.

Can you take the existing ones out? If so, leave the strongest one
sticking out as a pull-through, very carefully align the others to lay
straight and parallel to it, then heat shrink tube onto that bundle to
lock them together (much better than sticky tape). Finally, pull the
bundle through as single entity. That has worked for me when trying to
get too many cables through an existing hole in a wall. I lubricated it
with washing up liquid, as that was what was to hand.

Various options...

Others mentioned lubricants.

Draw them all in together, not one at a time.

Failing that, pull the others back the length of the duct (plus a bit),
and then push them all through together.

Push a draw wire/cane through, and pull the extra one back with it.

Get rid of one of the ethernets, and use an ethernet switch instead.

"(don't use graphite power - it conducts electricity!)"

True, but my first thought on reading that was "so does metal conduit,
which you might put cables through". On further reflection, though, I
guess the problem is that the graphite can get into other things like
the box at the end of the conduit --- is that sort of thing the
problem?

Hellerman Oil is what you need:

You could use miniature 75 ohm coax for one or more of them (it's OK for
satellite upto about 5 metres.)

I would have thought you'd pull the normal coax through though, with
care. Mr Sheen is very good as a lubricant.

Just put one of the Cat5 through, then a small switch or even hub the
other end.

Hellermann lubricant is brilliant for this sort of thing, available
from Farnell:

I have never tried it but other water-based lube would probably do
just as well and that can be bought in Poundland etc!

No, it is mineral oil based

http://servisol.co.uk/wwwcrc/msds/se...super%2010.pdf

Petroleum products are more likely to interact chemically with the
insulation, they will *probably* not do any harm, but it is more of a
risk than with silicone. Also they are inflammable.

Interestingly, this is *not* silicone. I rather suspect it is something
like KY Jelly with a fungicide; it will eventually dry out. I certainly
would not have any concerns over compatibility with a proper cable
lubricating product like this.

Sprays like this just produce a mist; toolstation has something similar.
The only downside is that they disperse a bit quickly. OTOH the silicone
fluid sold by Wickes etc for lubricating gutters, pushfit waste
fittings, etc is more persistant (but relatively expensive). A lot
depends on how quickly you will be able to finish the job.

I had to poke some coax through a tight hole. and Boots Moisturising
Cream worked fine.

What about Savlon? When replacing a car water pump on the side of the A1
in Yorkshire, I once used it as a jointing compound (plus a thin
cardboard gasket made from a box of tissues).

And has anyone mentioned WD40? I've never found WD40 adversely affect
cables in any way whatsoever.
