## Customer Reviews

### ⭐ 







  
  
    Not according to photo or description, size is correct however
  

*by J***T on Reviewed in the United States on July 2, 2019*

I ordered this seal because of the pictures showing the raised ring on both sides.  This is only the raised ring on the one side which fits into the groove on the flange.  It DOES NOT have a raised o ring on the other side.  So it is just flat on the one side.

### ⭐⭐⭐⭐ 







  
  
    They fit and didn't leak
