A fluid coupling 10 includes a first coupling member 11 and a second coupling member 12. The coupling members 11 and 12 are longitudinally movable relative to one another between first through fifth configurations illustrated in FIGS. 1-5 during a connection and disconnection sequence. The coupling 10 uses a locking sleeve 68 and locking balls 67 to facilitate connection and disconnection without tools. The coupling member 11 includes O-ring seals 26 and 27 carried on a sealing portion 24, and the locking balls 67 are radially spaced from the seals 26 and 27 during the connection and disconnection sequence to eliminate seal damage during the sequence. The first coupling member 11 includes a valve mechanism 41, 42, 43 and a fluid filter 46, and the valve mechanism is retained in place by the fluid filter 46. Cooperating valve mechanism 41, 42, 43, 63, 64, 65 includes a self-aligning valve poppet 64.
