The original gasket on this toilet had failed after 20+ years and I needed an instant replacement! I've taken it on myself to rebuild one from scratch for just $2 in TPU. I'm certain others will need this gasket as well considering the same part runs $25 at wal-mart and Ace hardware. As you can see, the old gasket was a real mess! The new one printed in TPU should last longer (30 years) Currently, it functions very well as a newly installed part.
