## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked great.
*by M***R on July 23, 2024*

Perfect fit for the job. This gasket is at least 50% larger than a gasket I had tried first that didn't work.

### ⭐⭐⭐⭐⭐ Fits American Standard tank with Flushmate 503 insert.
*by G***T on June 27, 2025*

Replaced faulty ring and fit perfectly. Easy installation. Ring slips over tank outlet and prevents misalignment.

*by A***R on August 4, 2025*

I have a Flushmate 503. Fit perfectly and fixed the issue.
