Patent ID: 8820798

Claim:
A connector assembly, comprising: a first connector defining a ring-shaped connector groove, said connector groove having an outwardly oriented radial first sealing surface and further having an inwardly oriented radial second sealing surface facing the first sealing surface; a second connector configured to connect with said first connector along a mating axis and defining a tapered sealing ring, said sealing ring having an inwardly oriented radial surface defining a first angle with respect to the mating axis and an outwardly oriented radial surface defining a second angle with respect to the mating axis; a ring-shaped interfacial seal received in the connector groove of the first connector and defined around the mating axis, said seal having: an inwardly oriented radial surface and forming an internal sealing portion that surrounds the first sealing surface of the first connector, an outwardly oriented radial surface and forming an external sealing portion that is surrounded by the second sealing surface, opposed top and bottom surfaces linking the internal sealing portion to the external sealing portion, and a seal groove defined in the bottom surface around the mating axis, said seal groove having a tapered profile and configured to receive the sealing ridge and having a radial outwardly oriented surface defining a third angle with respect to the mating axis and a radial inwardly oriented surface defining a fourth angle with respect to the mating axis, wherein when the sealing ridge is not received within the seal groove, the value of the first angle of the sealing ring is greater than the value of the fourth angle of the seal groove and the value of the second angle of the sealing ring is greater than the value of the third angle of the seal groove, wherein when the sealing ridge is received within the seal groove, the inwardly oriented radial surface of the sealing ring contacts the radial outwardly oriented surface of the seal groove and the outwardly oriented radial surface of the sealing ring contacts the radial inwardly oriented surface of the seal groove, thereby radially compressing the internal sealing portion of the seal against the first sealing surface of the first connector and the external sealing portion of the seal against the second sealing surface of the first connector.
