A fuel injector, which, at its inflow-side end, has an intake connector at whose outer circumference at least two sealing rings are provided, which seal the fuel injector from a valve seat. Due to an intermediate ring, the two sealing rings are axially set apart from one another in a respective ring chamber. The intermediate ring is embodied independently of the intake connector and is made up of two parts. A flexible outer ring is locked in place on an inner extruded support ring, the outer ring only being mounted once the first sealing ring has already been moved across the support ring and has been stripped off. The fuel injector is particularly suited for the use in mixture-compressing internal combustion engines having external ignition.
