Self Vulcanizing Tape

'cure' into a solid mass.

I think RS used to sell something similar, but have no idea what it would
be called.

You might try some industrial electrical supply houses.

Think it scotch #23 tape (and several other
numbers . Home Depot and Lowes has the stuff
(Not to be confused with "Coax Connector Sealant"
Radio shack # 278-1645, which is also great for
sealing connectors against the weather). Great for
weatherproofing, but needs to be covered (it
is ultravilot sensitive) But- NOT to use it to
plug holes! Dux Seal (a.k.a. "Monkey ****" is
MUCH BETTER-- Jim NN7K

Can anyone tell me what the official name of the putty they use to seal
the holes you run your coax through so bugs don't crawl in the wall or
water doesn't get in? I like to get all my hardware type items from
mcmaster.com. I'm sure they have it, if I just know what it is called I
can find it on their website.

I use the "expandable foam" that comes in a can about the size of a
spray paint can. There are two types. The yellow foam that expands
and gets hard which also is sensitive to UV which will cause it to
change color (darken). Don't use this around areas where the pressure
of expansion can cause problems like sealing around a door.

They also have a "soft/flexible" version that is white and costs a bit
more. It's what I use to block the large conduit between the tower
and basement. http://www.rogerhalstead.com/ham_files/cablebox.htm
Shows the conduit at the tower and coming in the basement. I just
squirted the stuff in. I wasn't worried about it being pretty, just
effective. With care you can be a lot more artistic. :-)) It's easy
to apply and easy to remove when necessary. Bugs and critters appear
to not like the stuff. I like it far better than the putty.

The yellow foam is a tad over $3 USD a can while the white, flexible
stuff is $4 or $5 a can. Both are usually available at Lowe's,
Builder's Square, and hard ware stores.

I was thinking "electrician's putty" or similar -- what we used to call
"monkey ****" in the Navy, but I couldn't get a good match on Google for
those terms. While mulling this over, I remembered also Plumbers Putty.
While generally not used for coax, I have used it under sinks and in the
garage for sealing around pipe penetrations. What I have is light tan in
color. It stays soft and flexible (but I don't know what sunlight does to
it or whether it will take paint). It's cheap and available and might be
just what you need.

Try DOW Chemical's "Great Stuff ", a "Tripple Expanding Polyurethane
Foam Sealant"
This comes in a paint spray size can and is applied withan attachable
tube.
It sticks to everything, as it goes in as a liquid then expands to fill
even large holes.
It firms up and seals tight. Cable companies around here use it. Even
works well on cinder block

I'm surprised to see Dow with such a product when it competes with Dow
Corning's compounds which are sold under the DAP as well as Dow
Corning names.

The various forms of expandable foam are easier to use, and to me work
far better than the putty and self vulcanizing tape. The Silastic
RTVs (TM) work well, but may be a bear to get out.

Altho, these may be easier to use than dux seal,
beware- if the stuff smells like Vinagar (as in
Ascetic acid) , you may be contaminateing your
coax, as is my understanding. And, MOST RTV's
have this feature (contaminateing your coax)!
Not a good situation! as info, Jim NN7K

Not usually a problem when going through a wall unless the outer insulation
is broken, but RTV is not may favorite for this. Plain old caulk works great
unless you have a big void to fill.

Jimmie already go this one, but if the seal is pretty much out in the
open it will not contaminate the coax jacket. Normally the stuff
won't bother the jacket any way, just don't apply directly to copper
or aluminum braid as the Copper will turn green.

OTOH there are versions available in Silicon that are
non-contaminating and there are also latex/water based versions. Most
of the DAP (TM) ( made by DC) is water based although you can specify
Silicon. Once cured there is not a great deal of difference although
there are some.
