Abstract: A quick disconnect apparatus including a first end configured to interface with a legacy fill and drain valve (FDV) of a satellite to be serviced, a second end configured to interface with a refueling tool, and a middle portion including at least one redundant seal to prevent unwanted fuel transfer during connection of the FDV and refueling tool.

Abstract: Disclosed herein is a system including an oxidizer nozzle tool having a first end, a rotary drive and a linear drive mechanism. A component, such as a quick disconnect valve, is attached to the first end of the oxidizer nozzle. The rotary drive actuates the component to engage and seal to a drain valve on a device (such as a satellite) such that the component can open and close the drain value while maintaining the seal, wherein the linear drive mechanism is operable to lock and release the component from the oxidizer nozzle tool. A hose is mated to the oxidizer nozzle tool, wherein upon actuation, fluid flows through the hose to the oxidizer nozzle tool and through the component into the drain valve.
