A hydraulic fluid system having a fluid shut-off valve assembly for controlling the flow of fluid from a reservoir to a pump. The shut-off valve assembly has a body coupled to the drain pipe of the reservoir. The body has a chamber accommodating a valving member that is moved with a rotatable member between open and closed positions. An annular elastic ring yieldably retains the valving means in the open position. The valving means is a tubular member having a fluid outlet passage and a head attached to the tubular member. When the valving means is in the closed position, the head blocks the flow of fluid through the fluid outlet passage. A connector is attached to the rotatable member for coupling a fluid carrying hose to the valve assembly.
