Please note: Not all Toto flappers are interchangeable for all models and your toilet may not flush properly if the wrong parts are used. Per the manufacturer, some flappers have been replaced on certain models, but remain the same on other models. We realize this can be confusing, so if you are unsure which flapper you need, please consult the parts diagrams for your model to ensure you are ordering the correct flapper.
