ABSTRACT:
An undersea hydraulic coupling having a male member with a stepped outer body is inserted into a female member having a bore with stepped internal cylindrical surface. The step in the male member defines first and second external cylindrical surfaces which are slidably received in the female member bore and in a sleeve member before the seals, which are retained by the sleeve member, engage the male member. Thus, the male member is more accurately positioned and guided into the seals, insuring greater seal reliability and longer seal life. The stepped surfaces also help prevent implosion of the seals due to sea pressure when the end of the male member comes out of the seals.
