https://www.korky.com/parts/fill-valve-replacements lists 2X Long Life Toilet Fill Valve, Part Number: 528X
I suspected maybe it was made with fiber filled plastic or something, and it would take the same R528 repair cap as the 528MP. This displaced most of the space where the silver-topped 528MP had been when I shopped.
However https://www.korky.com/products/fill...cessories/replacement-cap-assembly-fill-valve R528 lists that it "Fits 528, 528MP, 528T, 528GT, 528PRO". Maybe there will be a different cap for the 528X?
Any thoughts or insights?
