Aqua-Stop valve with handle.
Used in Fluval 104 / 105 / 204 / 205 / 304 / 305 / 404 / 405
Used to regulate filter output as well as to stop water flow during filter maintenance.
Please note that the Aqua-Stop Valve does come with two of the hose lock nuts (Item Q in the Parts Diagram).
There is an older style valve - which looks significantly different than this one - but rest assured that this part will fit!
For all 404 and 405 models.
