A fluid coupling assembly particularly adapted for connecting hydraulic conduits to the ports of a fluid manifold. The coupling comprises a male member which is threadedly connected to the port and which includes tapered locking surfaces on the male and female members, respectively, that are in tight frictional engagement when the male member is threaded into the female member. An O-ring is positioned in a pocket and disposed between the threads and the tapered locking surfaces to isolate the locking surfaces from hydraulic fluid, thereby ensuring a dry, frictional wedge lock. The O-ring is of a size that permits it to move axially in the pocket. In a modified embodiment of the coupling, there is provided an adjustable fitting which includes a lock nut having a skirt portion that is wedged into the tapered O-ring pocket.
