Claim 14:
15. A sealing interface, comprising:
a first tube having an end;
a spacer having 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 being attached to the end of the first tube, the second side of the spacer having a concave surface, 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;
a second tube having an end with a convex surface that substantially matches the concave surface of the second side of the spacer, the end of the second tube being disposed in an opposing relationship with the second side of the spacer so that the through hole of the spacer is in fluid communication with a fluid passageway of the second tube; and
a plurality of tying elements respectively coupled to the spacer and the second tube, the plurality of tying elements applying a compressive force between the second tube and the spacer,
wherein a flange extends from the outer surface of the spacer, the flange of the spacer having a plurality of holes defined therein, the end of the second tube includes a flange having a plurality of holes defined therein, and the plurality of tying elements is respectively coupled to the plurality of holes in the flange of the spacer and the plurality of holes in the flange of the second tube.
