Claim 0:
1. A sealing interface, comprising:
a first tube having an end with a convex surface;
a second tube having an end with a convex surface;
a spacer disposed between the respective ends of the first tube and the second tube, the spacer including a first side, a second side, and a third side that extends from the first side to the second side, the third side having an outer surface that defines an outer periphery of the spacer, the first side of the spacer having a concave surface that substantially matches the convex surface of the end of the first tube, the second side of the spacer having a concave surface that substantially matches the convex surface of the end of the second tube, and the spacer including a through hole that extends from the first side to the second side, the through hole being in fluid communication with a fluid passageway of the first tube and a fluid passageway of the second tube; and
a plurality of tying elements respectively coupled to the first tube and the second tube, the plurality of tying elements applying a compressive force between the first tube and the spacer, and the plurality of tying elements applying a compressive force between the second tube and the spacer,
wherein a plurality of projections is provided proximate to respective ends of the first and second tubes, the plurality of projections being spaced around respective outer surfaces of the first and second tubes, and wherein the plurality of projections includes tabs that extend from respective outer surfaces of the first and second tubes for a distance sufficient to clear an outer periphery of each of the respective ends of the first and second tubes, each of the tabs has a hole defined therein proximate to an outer end thereof, and the plurality of tying elements is respectively coupled to the plurality of holes in the tabs of the first tube and the plurality of holes in the tabs of the second tube.
