ABSTRACT:
The invention provides a method for moisture sealing the interface between a nut on the leading end of a male F-Type connector and the threaded tubular shaft of the female F connector. The male connector is attached to a coaxial cable and the female is mounted to an outdoor device such as a cable TV splitter, grounding device, satellite dish, or distribution device, amplifier or group. The sealing device includes a compressible portion comprising an elastically compressible member having a cylindrical bore and a conical outer surface. An annular compression ring overlies a portion of the conical outer surface of the compressible portion. The compressible portion is compressed radially inwardly against the shaft of the female F-Type connector as the leading edge of the male F nut is screwed onto the female threaded shaft of the female F-Type connector, providing a pressurized moisture ingress barrier. The compressible portion may have internal 3/8-32 threads to mate with threads on the shaft for a more secure seal.
