A small roll of Coax-Seal.  It is a putty like 
material in tape form. The white waxed paper 
keeps it from sticking to its self. 

Note that the first wrap comes back on itself 
exactly and the second turn starts the diagonal 
wrap.  Wrap from the coax cover toward the 
fitting with one half overlap with each winding.

 

The last wrap again comes straight back over the 
previous wrap without a diagonal. The seal is 
slightly sticky and should be molded now by hand 
to remove any gaps and to ensure that all the 
wraps are blending together. At some point the 
wraps will almost fuse together and the material 
may have to be cut away from the cable.

away from the connectors
