American Standard Screw On Flapper Disc 73383-0700

I was very happy to find this part and to be able to obtain it to fix a toilet in my parent's older home from the '60s. It fit perfectly and sealed tight. The old stopper had almost disintegrated and this was the perfect fix.

This is an exact replacement for a long out-of-production valve seal and was difficult to find. Other replacements do not meet the valve seat at the correct angle.
