Flappers en silicone American Standard Vormax 7381424-100.0070A

Fix perfectly.

Solved my problem in minutes. Installation was as easy as ever

Flappers worked great and easy to install. Nice to not have to call plumber to install

Bought it as a future replacement just in case. Better to buy original quality than roll the dice with some Chinese aftermarket part. Always kept a spare just in case and have never been let down or disappointed with American Standard parts.

The toilets were refilling several times a day. Replacing the gaskets fixed the problem as expected. Easily enough to install once you get the flapper assembly out of the toilet.
