Abstract
A shower head has a shell which is brass with a plated or painted finish. There is an exterior polyurethane coating to prevent corrosion. The interior of the shower head includes a water flow control with a spray former at one end thereof. A plastic sleeve is positioned against the inside of the shell and extends to and cooperates with the spray former to form a spray discharge pattern for the shower head. The plastic sleeve is required to avoid any adverse effect from the protective polyurethane coating or from a paint finish on the function of the spray former discharge openings.
