ABSTRACT:
An enclosure for encapsulating and sealing a cable includes a rigid, hollow cylindrical sleeve having an inner wall surface defining a chamber for receiving a portion of the cable therein. One end of the sleeve is sealably enclosed by an end seal and at the other sleeve end an end cap encloses the chamber. An inner disc is spaced longitudinally interiorly of the end cap to define with the end cap and with the inner wall surface, a cavity. An aperture is provided through the sleeve portion in registry with the cavity. Both the inner disc and end cap have apertures therethrough for passage of the cable. A sealing ring of mastic is sealably affixed around the inner wall surface of the sleeve and a sealing band of mastic is sealably affixed around the cable, the sealing ring and sealing band both contacting the inner disc at its longitudinally interior surface. The cavity is filled with expandable foamed polyurethane resin to urge the inner disc into pressing contact with the sealing ring and with the sealing band to thereby effect a seal therebetween.
