Abstract
An undersea hydraulic coupling member having a ring-shaped seal with multiple sealing surfaces extending radially inwardly therefrom is disclosed. The multiple sealing surfaces help guide the probe of the male coupling member into the female member without the risk of drag or galling of the receiving chamber or metal seal retained therein. The seal has an interfit with reverse inclined shoulders in the female member to restrain the seal from moving radially inwardly due to vacuum or low pressure. The seal also includes an internal biasing element to restrain the seal from moving radially inwardly during de-mating of the coupling members.
