A sandwich solenoid manifold assembly is provided which includes a steel plate having a plurality of fluid passages formed therethrough, a plastic manifold including a plurality of worm passages formed in a lower surface thereof and a plurality of insert receiving holes provided therein. The lower surface of the plastic manifold being connected to the steel plate. A plurality of steel inserts are inserted in the through holes in the plastic manifold, the steel inserts having a first end provided with a radial flange which abuts against a surface of the plastic manifold and a second end which abuts against the steel plate. The sandwich solenoid manifold assembly is less expensive to manufacture in comparison with conventional die cast solenoid manifolds.
