Claim Text:
1. A threaded connection comprising: a female component having interior threads, an operative end, a first shoulder disposed at the operative end, a second shoulder spaced from the first shoulder, and a sealing surface disposed between the first shoulder and the second shoulder; and a male component having exterior threads adapted for threadably engaging the female component, the male component having an end, wherein the end comprises a first complementary shoulder adapted to abut the first shoulder of the female component, a second complementary shoulder adapted to abut the second shoulder of the female component, and a complementary sealing surface disposed between the first complementary shoulder and the second complementary shoulder and adapted to seal against the sealing surface of the female component, wherein application of torque to the female component, the male component, or combinations thereof causes abutment between the first shoulder and the end of the male component comprising the first complementary shoulder to form a first radial seal between the female component and the male component, wherein application of torque to the female component, the male component, or combinations thereof causes abutment between the second shoulder and the second complementary shoulder to form a second radial seal between the female component and the male component, wherein application of torque to the female component, the male component, or combinations thereof causes contact between the sealing surface and the complementary sealing surface to form an axial seal between the female component and the male component, and wherein the female component and the male component comprise threads having a load flank with a negative angle relative to a longitudinal axis of the female component and the male component for enabling tension, compression, and bending of the threaded connection while retaining engagement between the female component and the male component.
