Claim 13:
14. A method of testing an interstitial space of a double-walled conduit, the interstitial space defined as the space between a primary pipe and a secondary pipe of the double-walled conduit, the double-walled conduit defining a longitudinal passageway, the method comprising:
positioning a compression ring circumferentially around the double-walled conduit;
positioning a seal circumferentially around the double-walled conduit and directly adjacent the compression ring;
inserting an interior fitting at least partially into the longitudinal passageway of the double-walled conduit; and
securing an exterior fitting circumferentially around double-walled conduit, such that a portion of the exterior fitting engages with at least a portion of the interior fitting and urges the compression ring to axially displace toward the seal, such that the seal creates sealed engagement between the interior fitting and the conduit;
wherein the exterior fitting is composed of a first and second exterior fitting, and securing the exterior fitting comprises:
positioning the first exterior fitting on a first side of the double-walled conduit,
positioning the second exterior fitting on a second side of the double-walled conduit,
engaging the first and second exterior fitting portions through compressing the portions against the double-walled conduit until openings of the first and second exterior fitting portions abut one another; and
securing the first and second exterior portions together with at least one bolt.
