Which component arrangement allows the Primary Air Supply Pack to connect via a quick disconnect?

• A. Flow divider valve
• B. Quick disconnect and gauge
• C. Electrical connector and relay
• D. Quick disconnect and valve

Answer: (D)

Connecting a primary air supply pack via a quick disconnect relies on having a rapid, leak-tight coupling paired with a valve to control or isolate the air when the pack is attached or removed. The quick disconnect provides the detachable connection, while the valve allows you to shut off or regulate flow during connect/disconnect, preventing a blast of air and preserving system pressure. A gauge alone would only show pressure and doesn’t enable the disconnect. A flow divider would alter distribution rather than enable the attachment. An electrical connector and relay pertain to electrical signaling, not the air line. So the arrangement that combines a quick disconnect with a valve gives the functional, safe connection for the Primary Air Supply Pack.
