Claim:
A coupling assembly comprising: a component having a surface, the surface defining a port opening for a port which extends into the component, wherein the port has first, second, and third diameters, which are at respective positions from closer to the port opening to further inside the port, the first diameter being larger than the second diameter and the third diameter being smaller than the second diameter, and wherein the port widens at an angle α between the third diameter and the second diameter, and the port widens at an angle β between the second diameter and the first diameter, the angle α being different than the angle β; a conduit having an annular bead, wherein an end of the conduit can be slidably inserted into the port such that the end of the conduit extends beyond the position of the third diameter and at least a portion of the annular bead extends beyond the port opening; and a seal extending around the conduit between the annular bead and the position of the third diameter.
