    Abstract: A seal kit for assembly into a system for sealing an elongate heating cable from ambient essentially includes a cone-shaped elastomeric grommet, several molded plastic parts, and a compression spring. The compression grommet forms a sealing interface between itself and a molded plastic enclosure body and between itself and an outer jacket of a heating cable. Cable ends are sealed within a sealed interior space of the enclosure body. A cup-shaped surface of a molded plastic part adjacently facing a congruent cone-shaped surface of the elastomeric grommet forms a slip-plane. The compression spring transfers energy to compress the elastomeric grommet and to cause it to expand radially against an interior wall of the enclosure body and against an outer jacket of the electrical cable and prevents that region of the grommet from becoming bonded over a high temperature operating interval to the inside wall of the enclosure body. When the sealing system cools down, the elastomeric grommet slips longitudinally along at least the slip-plane and thereby maintains a radial seal against the outer jacket of the heating cable.

    Abstract: An apparatus for sealing the end of an elongate cable such as a heating cable includes (1) a housing with a first open end and a second open end and a strain relief element positioned within the housing, (2) a flexible container which can be positioned over the cable end and (i) is of generally tubular shape, (ii) has an interior surface and an exterior surface, (iii) has a first open end and a second closed end, and (iv) contains a sealant; and (3) a cap which can be mated with the housing at the second open end, and cover the flexible container. The apparatus has excellent moisture-resistant properties even after repeated exposure to high temperatures, is reenterable, and can be readily mounted on a substrate such as a pipe.

    Abstract: An apparatus for sealing a core of an elongate cable in which a polymeric core of an insulating or a conductive polymer is positioned between first and second elongate electrodes. The apparatus is a container which has a first portion with an open end into which the cable can be inserted and a second partially closed end which has first and second openings. The first portion also contains a sealant, e.g. a grease or a gel. A first removable guide tube is inserted through the first opening and a second removable guide tube is inserted through the second opening, the first and second guide tubes being suitable for insertion of the first and second elongate electrodes, respectively. The apparatus allows insertion of the elongate electrodes after the polymer has been removed from them, without allowing contact between the electrodes and the sealant.
