Abstract
A drain valve to be used with numerous drain applications, such as draining fluid from an engine, includes in an exemplary embodiment a valve body, a first and second o-ring and a valve sleeve. The drain valve eliminates the need for a tool, such as a wrench, to drain the fluid from the engine, for example. The drain valve includes a twist-and-pull valve sleeve feature to manipulate the valve; however, the valve sleeve remains on the drain valve and therefore cannot be lost or misplaced. The valve sleeve further includes an easy grip for opening and closing the valve. The drain valve may include a notch formed on the valve body to serve as a break-away point to permit the valve to break under certain conditions.
