Plasson's Plastic Turf Valve & Key, provide a simple and convenient On / Off hose connection.  Place valves in strategic location along your buried lines.  The yellow lid snaps shut to prevent dirt from entering the system.  The male key is inserted into the valve which opens the connection and snaps into place.  When watering is done, just unsnap the key, the valve shuts, and the hose can be moved.

The connection of both the valve  & key is Male Hose Thread.
