Neoperl PCW-02 Washer Regulator for Shower Heads

The PCW-02 washer regulator can be used to replace the washer in 1/2" shower handles, bib and pillar taps with a male thread. Its dual function is to seal and to regulate the flow. With a flexible turbine for secure positioning, the PCW-02 fits in various tube diameters.
This washer regulator offers a convenient way of saving water and energy by keeping the flow rate constant regardless of changes in line pressure. This also means that where more than one appliance is used at the same time, the PCW-02 maintains an even water distribution.
