What it is

The Roca A543356407 is a single flush diaphragm washer, supplied as a service component for Roca single flush valve assemblies. It sits within the flush mechanism as a flexible sealing diaphragm, separating the pressure chamber from the flush outlet. Its role is to flex and seat correctly so the flush cycle initiates and shuts off as designed.

Before you order

  • Confirm the part number A543356407 matches the component being replaced.
  • Check that the valve assembly is a single flush type, as this diaphragm is specific to that configuration.
  • Inspect the diaphragm seat and housing for scale or debris before fitting, as contamination affects sealing.
