Not sure the age of your toilet?
 
1. Look for your toilet's data label. Poke your head through the toilet access door, you may find it on an inside wall where the holding tank is located.
2. Note the Code # on the label. This 6 digit # is actually the date of manufacture YY MM DD
 
Please be thorough when identifying lip seal as we cannot accept returns of toilet parts.
