ABSTRACT:
An improved hydraulic coupler suitable for interconnecting subsea fluid lines is provided with a radial seal between the male and female body portions. A C-shaped metallic seal is housed between the female body of the coupler and a retainer external of the female body. An elastomeric secondary seal is provided on the retainer, and sealingly engages the same diameter cylindrical surface of the male coupler which is engaged by the C-shaped seal. A wiper member also mounted on the retainer cleans this cylindrical suface as the body portions are brought together, thereby enhancing the reliability of both the elastomeric seal and the metallic seal. Coupler halves may typically be housed within either a latchable subsea control module mounting base or a junction plate conventionally used in surface petroleum recovery operations.
