Claim 5:
6. A sealing interface, comprising:
a connected component having a first end, a second end, and an internal passageway extending from the first end to the second end, the first end being configured to be connected to a fluid source so that a fluid from the fluid source is guided away from the source through the internal passageway of the connected component, the second end including a convex surface and a flange, the flange having a plurality of holes defined therein;
a tube having an end with a convex surface and a flange, the flange having a plurality of holes defined therein;
a spacer disposed between the second end of the connected component and the end of the 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 second end of the connected component, the second side of the spacer having a concave surface that substantially matches the convex surface of the end of the 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 the internal passageway of the connected component and a fluid passageway of the tube; and
a plurality of tying elements respectively coupled to the plurality of holes in the flange of the connected component and the plurality of holes in the flange of the tube, the plurality of tying elements applying a compressive force between the connected component and the spacer, and the plurality of tying elements applying a compressive force between the tube and the spacer,
wherein the second end of the connected component has an annular channel defined therein, and a sealing member is disposed in the annular channel defined in the second end of the connected component so that a portion of the sealing member is in the annular channel and a portion of the sealing member is in contact with the first side of the spacer.
