Armitage Shanks / Ideal Standard Hushflow (quiet) toilet cistern fill / float valve diaphragm washer.
Suits the older screw cap style of inlet valve / ball-cock supplied with many Armitage and Ideal Standard toilet cisterns. It won't fit the newer "Univalve" twist top valve.
May have white or red plastic centre nipple (apparently this is a colour coding system used in the factory to identify different batches).
Please study all picture(s) very carefully to make sure you are buying the correct washer.
If your old washer has 18 little ridges pressed into the rubber, then you need the "Univalve" diaphragm - NOT the one we are selling here. They are not interchangeable.
