ABSTRACT:
A seal assembly permitting a conduit member to be sealed within a bore in metal-to-metal relationship wherein a seal ring of a conical configuration in the relaxed state is deformed toward a flattened condition to increase its radial dimension and establish sealing under the influence of the pressurized medium of the system with which the seal assembly is employed. The relaxed state of the seal ring permits insertion and removal of the conduit into the bore without scoring, and the seal ring characteristics establish effective high pressure sealing while capable of accomodating limited lateral and axial displacement.
