Abstract: A quick disconnect coupling is disclosed for releasably interconnecting first and second fluid flow members each having a fluid opening. The coupling includes a base member having a bottom surface, an annular attachment collar defining an inner fluid port axially through the base member and including an outer cylindrical side wall, and an annular shoulder surrounding the attachment collar. A mechanism is provided for mounting the base member bottom surface to the first fluid flow member in order to align the fluid port with the fluid opening of the first fluid flow member. A connecting plate is further provided having a top and bottom surface and a central aperture defining an inner cylindrical sleeve sized for journaling about the collar side wall for limited rotation thereabout. The connecting plate also includes an inner annular shoulder disposed along the bottom surface radially outwardly of the sleeve, the connecting plate upper surface being adapted for connection to the second fluid flow member.
