Two propellant quick disconnect ports shown: fully assembled (at left), and disassembled.
Used throughout the Apollo Command and Service Modules for propellant loading and testing.
Port at left had been installed in Spacecraft 117, the second Skylab mission. It was removed before
the flight because of a leak detected in testing.
Disassembled port was removed from Spacecraft 114, the Apollo 17 mission, before its flight. It also
was removed because of a leak, then taken apart for analysis.
