An externally threaded male hydraulic coupling member (20) adapted for threaded and sealed attachment to a port body (70) with a female port (71). The male coupling member (20) having a tubular member (35) with a threaded end (30), a bore (23) extending through the member (35), a first cylindrical peripheral undercut portion (60) longitudinally adjacent the threaded end (30), a series of intermediate external threads (55), and a second cylindrical undercut portion (34). The coupling member (20) having a seal member (40) and an annular ring member (45) located in peripheral sealing contact with the first undercut portion (60). Wherein upon attachment, the seal member (40) is encapsulated by the annular ring (45), the female port (71) and the first undercut portion (60) forming an annular chamber (80) having a longitudinal extent greater than the seal member (40) thickness. The coupling member (20) also having a lock nut (50) threadedly attached to the intermediate threads (55) with a longitudinal end (51) located between the annular ring (45) and the intermediate threads (55). The lock nut (50) having a longitudinal extent greater than the axial length of the intermediate threads (55) and the second undercut portion (34).
