A Guide for the Selection of Quick-Disconnect Couplings for Aerospace Fluid Systems
The factors involved in the selection of a quick-disconnect are grouped into the following classifications for the purpose of discussion: a. functional considerations; b. weight considerations; c. environmental performance factors; d. end fitting types; and e. additional considerations. A quick-disconnect coupling as used in this AIR is one that can be rapidly and repetitively connected and disconnected without excessive fluid loss. The relative importance of the design factors depends upon the fluid medium of the particular system in which quick-disconnect is to be used. The effect of the fluid media on each factor is discussed in this report where applicable. The purpose of this AIR is to guide users in the proper selection of quick-disconnect couplings for their specific application in fluid systems.
