   I moved recently to Boston.  When working with the telephone company 
engineers to install my phone service, I noticed that my
network interface unit contained an unusual, non-sticky, clear, semi-solid 
material ("UNSCSSM").  The striped, bare ends of the
copper wires were inserted into this material, which surrounded the screw 
clamps used to connect the wiring together.

   This UNSCSSM flowed around the screw and wires, preventing water and oxygen 
from reaching the exposed wire.  Wires that had been
immersed in the UNSCSSM were readily pulled out, and were still bright and 

   Offhand, it seems that a piece of heat shrink tubing containing this stuff 
could be shrunk around a coax connector, forming an
air- and water-tight seal.  If the connector needed to be undone, the heat 
shrink can be clipped off and the UNSCSSM peels away with
no residue.  It seems ideal for those tricky places like coax connections to 
SO-239 sockets on external boxes, where it's very
difficult to wrap tape around the socket in such a way as to be watertight.

   Does anyone know more about this material?
