An in-line filter is disclosed for filtering fluid flowing through a hydraulic system, particularly an automotive hydraulic system. The filter has a magnetic base with a central opening at its outlet and a seat with a central opening at its inlet. The base and the seat are joined by a cylindrical filter element made of a magnetically susceptible mesh screen material. A spring within the filter element biases a ball against the central opening of the seat normally sealing off the opening and forcing fluid to flow through the filter element to be filtered. If the mesh screen becomes clogged, backpressure forces the ball away from the seat against the bias of the spring to allow fluid to bypass the filter element and flow directly through the filter. Ferrous debris within the fluid flow continues to be captured by attraction to the magnetic base and the magnetized filter element.
