Split cable seal

A cable seal comprising:

• a threaded body, a compression plate, an outer nut, a compressible inner gasket, a compressible outer gasket and an inner nut;
• the threaded body including first and second halves which cooperate to form a generally cylindrical body with a central axial opening and a threaded outer surface, the body having a first end and a second opposite end, the first end including a continuous circumferential ring and a plurality of arms extending from the ring to the second end, an outer surface of each arm threaded and defining a portion of a circle, the central axial opening including an internally extending ledge within the ring adjacent the first end;
• the compression plate including a pair of halves which cooperate to form a generally flat plate having an outer surface and an inner surface and with a central axial opening defined by a central cylinder, the compression plate including a plurality of openings sized to receive the arms of the threaded body so that an inner surface of the arms is adjacent the central cylinder of the compression plate and the arms extend through the plate;
• the inner gasket positioned within the central axial opening of the threaded body and including a central axial opening aligned with the central axial opening of the threaded body, the inner gasket including a generally cylindrical core entirely within the threaded body and extending from a first inner end to a second outer end and a radially extending flange at the second end, the flange including a plurality of openings aligned with the openings of the compression plate and through which the arms of the threaded body extend, the second end of the inner gasket engaging the inner surface of the compression plate and the first end of the inner gasket engaging the ledge within the threaded body, the inner gasket split to provide access to the central axial opening through a side wall of the inner gasket;
• the inner gasket positioned within a central opening of the outer gasket with the outer gasket adjacent the flange, the outer gasket including a plurality of openings positioned about the central opening aligned with the openings of the flange and through which the arms of the threaded body extend, the outer gasket including an outer edge in which is formed a groove, the outer gasket including an inner face and outer face, and a slit from the outer edge into the central opening;
• the outer nut including a pair of halves releasably attached to each and threaded about the second end of the threaded body, the outer nut engaging the outer surface of the compression plate, and the inner nut including a pair of halves releasably attached to each and threaded about the second end of the threaded body, the inner nut engaging the inner face of the outer gasket;
• wherein advancing the outer and inner nuts toward each other about the threaded body compresses the flange of the inner gasket between the compression plate and the outer face of the outer gasket, forming a seal between the two gaskets about the central opening of the outer gasket and also compresses the groove in the outer edge of the outer gasket;
• and,
• wherein advancing the outer nut toward the first end of the threaded body compresses the core of the inner gasket between the compression plate and the ledge of the threaded body causing the central axial opening of the inner gasket to reduce in diameter.
