Abstract
A method and apparatus for attaching a first component which comprises a depending portion to a second component which comprises a bore that is sized and configured to receive the depending portion, wherein the first and second components are exposed to a fluid which is at an ambient pressure, comprises the steps of inserting the depending portion at least partially into the bore and then creating a bore pressure within the bore which is less than the ambient pressure. In this manner a pressure difference between the ambient pressure and the bore pressure will force the depending portion into the bore to thereby attach the first component to the second component.
