A drainage assembly () includes a first segment (A) with a first inner tube (A) defining a first inner tube passage (A), a first outer tube (A) concentrically disposed around the first inner tube (A) and defining a first outer tube passage (A), and a first fitting (A) disposed on an end of the first segment (A). The first fitting (A) has a first inner passage (A) in fluid communication with the first inner tube passage (A) and a first outer passage (A) in fluid communication with the first outer tube passage (A). A plate () is positioned adjacent the first fitting (A). The plate () has a second inner passage () in fluid communication with the first inner passage (A) on one side, and a second outer passage () in fluid communication with the first outer passage (A) on the one side. Also included is a drainage line () in fluid communication with the first outer tube passage (A).

A fitting for connecting tubular assemblies includes a base member defining a first bore configured to receive a tube therein. A retaining band defines a second bore for receiving a portion of the base member. The retaining band defines an engagement feature on a radially outward surface configured to engage a locking mechanism of a fastening member.
