Sloan 3378021 Urinal Flushometer Diaphragm Vortex

Product Description

The SLOAN 3378021 is a synthetic replacement diaphragm with disc designed for Vortex-style urinal flushometers. The diaphragm assembly controls the flush cycle by regulating water flow through the valve body — when it fails or wears, the flushometer may run continuously, fail to flush, or produce an incomplete flush cycle. This part is constructed from synthetic material for durability in high-cycle commercial restroom environments. Licensed plumbers and facility maintenance technicians are the typical installers. At 0.054 pounds, the assembly is compact and straightforward to swap during a standard valve rebuild.

This diaphragm with disc is suited for commercial and institutional urinal flushometer service. It is the correct internal rebuild component for Vortex-type SLOAN urinal valves. Typical applications include restroom fixture maintenance in office buildings, schools, hospitals, and other facilities running SLOAN flushometer-style urinal valves. This part is commonly replaced during a full valve rebuild or when diagnosing continuous-run or no-flush conditions in the valve.

Installation Notes

Installation should be performed by a licensed plumber or qualified maintenance technician.
