ABSTRACT:
A high pressure fitting system includes a body having a passage therethrough to provide fluid communication between an associated fluid system and a female port. The body includes a first groove adapted to receive a seal member that defines a primary seal when inserted in the female port. A frusto-conical portion on the body cooperates with a frusto-conical region of the female port to define a secondary metal-to-metal seal. A second groove in the body receives a pressure transfer ring which is partially captured by a fastening sleeve freely received around the body. Rotation of the fastening sleeve results in axial advancement of the male fitting assembly via the pressure transfer ring to establish the secondary seal.
