Abstract

A filter head may include a receiving component and a threaded metal nozzle insert at least partly injected into the receiving component. The receiving component and/or the filter head may be composed of plastic. The threaded metal nozzle insert may be structured as a cold extruded part. A plurality of radially extending ribs may be disposed in a cavity of the receiving component and/or the filter head. The ribs may be composed of plastic and/or integrally formed with the filter head. The ribs may extend along a radial direction from the threaded nozzle insert to a wall of the cavity. The ribs may additionally lead radially outward into an axial sealing surface of the filter head.
