ABSTRACT:
A high pressure connector for engagement with a hydraulic conduit for use in high pressure conditions such as downhole in a wellbore. A housing for receiving a conduit end is attachable to a primary retainer. A primary seal and a second seal are positioned between the primary retainer and the housing to provide redundant sealing capabilities. A secondary retainer holds a third seal against the primary retainer. The third seal provides redundant sealing capability and further provides a secondary gripping connection along the conduit length. The secondary gripping connection provides greater tensile strength and reduces the impact of conduit vibration. A test apparatus can be adapted to test the primary seal and the second and third seals before the connector is installed downhole in the well or other high pressure environment.
