Description of Driving Event:

The QD/filter assemblies are designed to provide a disconnect interface and remove all solid particles (exceeding 25 microns) from the servicing fluids at various system operating pressures, contaminant capacities, and rated flows. Servicing fluids include O2, H2, freon, coolant water, and potable water. Assemblies consist of a quick disconnect, filter, and associated caps, fittings, seals, and tethered nameplate/identification tags. The QD has internal bellows which permit movement of a probe assembly that opens flight-half coupling. A pod component failure may cause contamination in the orbiter onboard reactants.
