Abstract
Overmolding of softer materials onto ends of rigid plastic pipes is detailed. The pipes typically are components of automatic swimming pool cleaners and connect to valves made of softer, flexible material. Because of the overmolding, flexing of the valves during operation of the cleaners does not cause significant wear of the valves in the regions where they connect to the pipes.
