Abstract
A female hydraulic coupling member has a pressure-energized C-seal having an internal cavity that is positioned to seal between the body of the coupling and the probe of a corresponding male hydraulic coupling member inserted in the receiving chamber. A metal sleeve lines at least a portion of the receiving chamber to resist galling. The main portion of the sleeve has an inside diameter (i.d.) and an outside diameter (o.d.) with a first end of the sleeve abutting a shoulder in the central axial bore of the coupling member. An opposing second end of the sleeve has an annular, axial extension with a larger i.d. and a smaller o.d. than the main portion of the sleeve. At least a portion of the extension projects into the internal cavity of the pressure-energized C-seal so as to retain and position it.
