A pressure balanced hydraulic coupling for use in undersea drilling and production operations is shown. The coupling has radial passages connecting between the male and female members such that fluid pressure is not exerted against the face of either member during coupling or uncoupling. The female member has a split body with a first part and a second part, each having a longitudinal passage and a radial fluid passage. A radial seal is positioned on the junction between the first and second parts of the female member body to facilitate removal and replacement of the radial seal when the split body is disassembled. The male member may be inserted through the first and second parts of the female coupling member, thereby establishing fluid communication between the coupling members in a direction transverse to the coupling member bores.

[ What is claimed is:] [11.] An undersea hydraulic coupling, comprising:(a) a male member having a longitudinal fluid passage connected to a radial fluid passage;(b) a female member having a split body with a first part and a second part removably engaged to the first part, a central bore dimensioned to receive the male member, the first part and second part each having a longitudinal fluid passage connected to a radial fluid passage, the longitudinal fluid passages of the first and second parts being interconnected when the second part is engaged to the first part, each of the radial fluid passages extending between the longitudinal fluid passages and the central bore; and(c) at least one radial seal positioned between the first part and second part of the female member, the radial seal removable by separating the first part and second part of the female member. [12.] The undersea hydraulic coupling of claim 11 further comprising first and second valves in the male and female members respectively, the valves having actuators extending therefrom, the valve actuators mutually engageable when the male member is in the central bore of the female member to open the first and second valves.
