ABSTRACT:
A fluid coupling for use with plural conduit system manifolds wherein a plurality of couplings are mounted upon common support structure. Each opening incorporates alignment structure permitting a limited degree of self-alignment to insure efficient sealing between the coupling parts. The alignment structure includes biasing means for maintaining axial alignment and sealing pressures, and radial clearances and elastomer members are employed to permit radial alignment.
