for many years I used the self amalgamating rubber tape like Coax Seal 
http://coaxseal.com/products/ with a couple of layers of good quality 
vinyl electrical such as Scotch super 33+ tape over top.

Scotch also sells a product called Linerless Rubber Splicing Tape 130C 
which is similar in use to Coax Seal which I now use in preference to 
Coax Seal. Nothing wrong with the Coax Seal product but I can get the 
Scotch products at the local Home Depot.

However, for the past 10 years or so I have been using double wall 
adhesive lined heat shrink tubing. My local electronics and electrical 
supplies carry this product and it is not that expensive. This I find 
both quicker to install, neater, more reliable, and much easier to 
remove than the rubber tape followed by vinyl tape method.

As Mark noted, there are also products for use in direct burial 
applications but I have no first hand experience with those specific 
products. I have buried splices for my own use by using a layer of 
double wall heat shrink with adhesive followed by a layer linerless 
rubber splicing tap and vinyl tape. I have not had an occasion to dig up 
any of my spliced cables so I don't know how they have held up but so 
far they have not failed in any way that I can tell.

cheers, Graham ve3gtc

You run the cable through the core and pull on a tab which unwinds the core and the stretched silicone collapses and forms a water tight seal.
