This is the Sloan WES-150 Hybrid Cartridge for WaterFree Urinal, Compatible with All S, a genuine Sloan replacement part for servicing a Sloan flushometer. Swapping the diaphragm, handle, or internal kit brings a worn or running valve back to a crisp, water-tight flush — the reason Sloan valves last for decades.
Using the matching factory part keeps the flush volume and performance to spec, and the repair takes minutes with basic tools. Match the part number to your valve model for a correct fit.
Sloan Valve Company has manufactured commercial plumbing systems in the USA since 1906, from its Franklin Park, Illinois headquarters — the company that invented the modern flushometer and remains a leader in water-efficient commercial restroom fixtures.
