I was asked to post this again, so here goes....
Hello All,
I recently received several requests from people on the list
wanting to obtain the large heat shrink I use to seal the Comet
and Diamond fiberglass antenna joints with. This stuff is great
for sealing connectors, antenna joints, covering shovel and
sledge hammer handles and covering tool handles like large
Crescent wrenches.
This shrink has an inert sealant that melts as the heat is applied
for shrinking. This creates a good (won't leak if it was drug
across the Atlantic) seal. Well maybe not that good......but damn
good.
It is available from Jerry Conn Associates Inc.
They are located in Chambersburg Penna.
The manufacturer is CANUSA. Pronounced canoosa.
The available sizes (unshrunk of course) are indicated by the
model number.
Example: Part number;
CFTV-400 is .4" (that's point 4 inches)
CFTV-1100 is 1.1" diameter
CFTV-1300 is 1.3" diameter
CFTV-2050 is 2.05" diameter and so on
These come in a 4 foot length.
I believe the shrink percentage is 50% of original, This is not
fact however.
I don't remember the spec. on shrinkage off hand... but it does
shrink a lot.
These are the available sizes:
The ones with pricing are normally in stock.

The CFTV-750 is great for RG-8/PL-259's or Type N connectors.
In our business, we use a propane torch to shrink the tubing. It's
wall thickness is very good, and not easily damaged by a
little excess heat. You can actually catch it on fire and not
damage it badly. It doesn't shrink well in windy conditions,
(requires lots of propane) In severe wind I use MAPP gas as it
gets burns hotter than propane, although this is usually not
necessary. I have used this stuff for years and can attest to its
quality if installed properly. There are other cheaper brands of
this stuff than CANUSA , but (in two words) they suck. There is no
equivalent. I tried them all.
Here is a pix of the stuff we use in the catv industry.

They also have a good quality Self Amalgamating Tape that is much
better for covering connections than Black Tape.
