摘要： An apparatus (1) for sealing the end of an elongate cable (73) such as a heating cable comprises 1) a housing (3) with a first open end (5) and a second open end (7) and a strain relief element (27) positioned within the housing, 2) a flexible container (43) which can be positioned over the cable end (75) and (i) is of generaly tubular shape; (ii) has an interior surface (53) and an exterior surface (55); (iii) has a first open end (47) and a second closed end (49); and (iv) contains a sealant (77); and 3) a cap (61) 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. Also disclosed is an apparatus (80) for sealing a core (103) of an elongate heating cable (101). The apparatus comprises a flexible container (81) in which a first portion (83) is attached to a second portion (89) which comprises first and second leg portions (91, 93) suitable for insertion of first and second elongate electrodes (105, 107) of the heating cable.

摘要： A seal kit for assembly into a system for sealing an elongate heating cable (134) from ambient essentially includes a cone-shaped elastomeric grommet (112), several molded plastic parts, and a compression spring (108). The compression grommet (112) forms a sealing interface between itself and a molded plastic enclosure body (104) and between itself and an outer jacket of a heating cable (134). Cable ends are sealed within a sealed interior space of the enclosure body. A cup-shaped surface (120) of a molded plastic part adjacently facing a congruent cone-shaped surface (118)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 slip-plane and thereby maintains a radial seal against the outer jacket of the heating cable.
