| Structure |
| When disconnected |
| The socket and plug valves seal instantly, automatically shutting off fluid flow to prevent leakage. |
|
| When When connected |
| The socket and plug valves push together, opening to permit free flow of fluid through CUPLA.An O-ring in the socket seals the plug surface preventing any leakage. |
|
| |
| Interchangeability |
- Different size sockets and plugs are not interchangeable.
