Abstract
A termination fitting assembly for use with a conduit includes the conduit comprising a primary pipe positioned centrally within a secondary pipe along a longitudinal axis of the conduit and the conduit having an interstitial space defined between the primary pipe and secondary pipe. The termination fitting assembly includes an interior fitting having an inner wall and an outer wall, the inner wall sized and shaped for insertion into and sealing with the primary pipe, and the outer wall extending circumferentially around the secondary pipe of the conduit. The termination fitting assembly includes an annular channel defined between the inner wall and the outer wall of the interior fitting and in fluid communication with the interstitial space of the conduit and an exterior fitting positioned around the conduit.
