| Structure |
| When disconnected |
| Characteristically, there is an extremely slight leakage when CUPLA is disconnected due to the metal seal system but it is not a functional problem. |
|
| When When connected |
| Since there is no packing used in the valve, there is no packing wear even if flow velocity changad quickly. |
|
| |
| Interchangeability |
- Different size sockets and plug are not interchangeable.
