Abstract
A connector for connecting a heat exchanger tube to a heating vessel bulkhead, includes a connector housing, a sealing and locking nut, and a first and second o-ring. The connector housing includes a first conduit having an exterior surface, on which are formed a threaded portion, a peripheral bulkhead seating surface, and a first o-ring receiving cavity, such that the first o-ring receiving cavity is positioned between the threaded portion and the peripheral bulkhead seating surface. A bulkhead sealing ring has a second o-ring receiving cavity. A second conduit has a cross-section corresponding to the cross-section of the heat exchanger tube. The sealing nut engages the threaded exterior of the first conduit, and the locking nut engages and locks the sealing nut against the exterior surface of the bulkhead. The first o-ring is positioned within the first o-ring cavity, and the second o-ring is positioned within the second o-ring cavity. The second o-ring is sealed against an interior surface of the bulkhead, and the sealing nut seals the first o-ring against an exterior surface of the bulkhead. The sealing ring has a first port and a second port, such that the first port and the first conduit share a first longitudinal axis. The first port adjoins a first end of the first conduit adjacent to the peripheral bulkhead sealing surface. The second port adjoins a first end of the second conduit.
