An improved seal retainer for an undersea hydraulic coupling member, which utilizes metal seals to maintain fluid integrity, is disclosed. The metal seals of the present invention are designed to either create an absolute barrier to fluid flow, or utilize a press or interference fit to create a barrier to fluid flow to ensure fluid integrity between the undersea hydraulic coupling and the environment outside the hydraulic coupling.

What is claimed is: 1. A female undersea hydraulic coupling member comprising: a body having an internal bore and a shoulder intermediate the bore; a seal retainer insertable into the bore to abut the shoulder, the seal retainer having an outer shell and an inner seal carrier, the inner seal carrier sliding into the outer shell and having an integral metal blade seal positioned such that the blade seal contacts the shoulder intermediate the bore when the seal retainer is inserted into the bore; and, an annular seal positioned on the seal carrier, the annular seal insertable into and removable from the female undersea hydraulic coupling. 2. A female undersea hydraulic coupling member as recited in claim 1 wherein the integral metal blade seal comprises a pair of concentric, annular metal blades. 3. A female undersea hydraulic coupling member as recited in claim 2 further comprising an elastomeric seal retained between the pair of concentric, annular metal blades. 4. A female undersea hydraulic coupling member as recited in claim 3 wherein the elastomeric seal is an O-ring seal. 5. A female undersea hydraulic coupling member comprising: a body having an internal bore and a shoulder intermediate the bore; an annular groove in the shoulder, the groove having side walls and a bottom surface; a seal retainer insertable into the bore, the seal retainer having an outer shell and an inner seal carrier, the inner seal carrier sliding into the outer shell and having an integral metal blade seal positioned such that the blade seal contacts a side wall of the annular groove in the shoulder intermediate the bore when the seal retainer is inserted into the bore; and, an annular seal positioned on the seal carrier, the annular seal insertable into and removable from the female undersea hydraulic coupling. 6. A female undersea hydraulic coupling member as recited in claim 5 wherein the integral metal blade seal is tapered. 7. A female undersea hydraulic coupling member as recited in claim 6 wherein at least one side wall of the groove is angled at approximately the same angle as the taper of the blade seal to provide an interference fit between the blade seal and the side wall of the groove when the seal carrier is fully inserted in the bore. 8. A female undersea hydraulic coupling member as recited in claim 7 wherein the groove and blade seal are sized such that the blade seal contacts the bottom of the groove when the seal carrier is fully inserted in the bore. 9. A female undersea hydraulic coupling member as recited in claim 5 wherein the integral metal blade seal comprises a pair of concentric, annular metal blades. 10. A female undersea hydraulic coupling member as recited in claim 9 further comprising an elastomeric seal retained between the pair of concentric, annular metal blades. 11. A female undersea hydraulic coupling member as recited in claim 10 wherein the elastomeric seal is an O-ring seal. 12. A female undersea hydraulic coupling member as recited in claim 11 wherein the elastomeric O-ring seal is in sealing engagement with the bottom of the groove when the seal carrier is fully inserted in the bore.
