Abstract:
1. A connecting block, comprising: a first member having first and second flow headers extending from a sealing surface, a planar interior face oppositely facing with respect to the sealing surface, and a perimeter wall perpendicularly oriented with respect to the sealing surface; a second member slidably received within the perimeter wall of the first member, the second member having a planar end face in contact with the planar interior face of the first member, a first flow member receiving bore axially aligned with the first flow header, and a second flow member receiving bore axially aligned with the second flow header; and a material of the second member being corrosively sacrificial with respect to a material of the first member; wherein the first member includes at least one aperture extending through the first member and the sealing surface, the at least one aperture allowing air to escape when the second member is slidably received within the first member, the contact between the planar end face of the second member and the planar interior face of the first member blocking the at least one aperture; and further including a bonding zone created by heating both the first and second members until the planar end face and the planar interior face melt or fuse together to create a physical connection between the first and second members; and wherein the bonding zone is electrically conductive; and wherein the bonding zone seals a perimeter of the at least one aperture.
