Abstract: A filtering device for fluids which includes a barrel with an open end and a flow discharge end. A plunger is slidably disposed in the barrel through the open end toward the discharge end and an exhaust nipple projects from the discharge end. The nipple is in communication with the interior of the barrel. A filter is disposed adjacent the barrel inwardly of and adjacent to the discharge nipple, and an annular, integral support stand is disposed at the discharge end of the barrel and surrounds the nipple. The nipple terminates at a point spaced from a planar surface defined by the support stand, which surface is normal to the axis of the barrel and the direction of movement of the plunger whereby the device will stand on a surface with the exhaust nipple spaced from the surface.
