ABSTRACT:
This invention discloses a method and apparatus for waterblocking wire-to-wire connections in a cable using an arrangement of seals. Lead-in transmission lines are slid through a multiple-aperture seal to produce a compression seal between the transmission lines and the seal and the trailing transmission line is slid through a single-aperture seal to produce another compression seal. A piece of constrictive tubing is slid over the first seal before splicing the wires in the lead-in and trailing transmission lines together. The tubing then is positioned over both seals to produce a compression seal between the tubing and the seals to form a waterblock in the area defined by the two seals containing the splice.
