Title: Method and apparatus for retaining seals

Abstract: An annular E-seal is installed in a retainer ring in such a way as to have limited degrees of freedom in the radial and axial directions while being retained in a groove of the retainer ring during component assembly and disassembly. The relative diameters of the retainer ring and the seal leg are such that installation or removal of the seal can only be accomplished by a deliberate tipping of the seal leg in such a way as to reduce its effective projected radial height. Thus, once installed, the seal is connected to and remains with one of the elements defining the gap to be sealed.
