| Structure |
| When disconnected |
The socket valve
provides an instant
seal, automatically
shutting off fluid flow
to prevent leakage. |
|
| when connected |
The plug and socket
engage securely, fully
opening valve auto-
matically to assure
maximm fluid flow.
The O-ring presses
against the outer-
|
|
| cylinder of the pulg forming a seal that prevents leakage. |
