Details
Over time, the seal diaphragm in a flush valve can wear or harden, causing leaks or weak flushing. Replacing it with a genuine Dudley 323306 diaphragm washer restores full sealing integrity and smooth operation. Compatible with the Niagara New Style dual-flush valve found in many modern Dudley concealed and exposed cisterns.
Compatibility tip: If your valve was fitted before 2016, please check whether you have the “New Style” Niagara before ordering, as seals differ slightly from older models.
