An injector for the metered ejection of a fluid, in particular fuel, has a housing and a plastic extrusion coating, which encloses the housing, and from which the housing protrudes at an upper housing end on the fluid inlet side and at a lower housing end on the fluid ejection side. To achieve a so-called “fording capability” of the injector, the peripheral separation point of the housing and the plastic extrusion coating, at the lower end of the plastic extrusion coating, is sealed, preferably with the aid of a sealing collar.
