## Customer Reviews

### ⭐ 1.0 out of 5 stars







  
  
    Appears to have a manufacturing defect...
  

*by A***R on Reviewed in the United States on August 29, 2020*

I received this valve seal today.  Although it appears to be in a factory-sealed card, there is a big chunk of the seal edge missing -- not very reassuring for a toilet flush valve.  (See arrow on attached photo.)  Also there appear to be scuff marks across the seal rubber.  Not sure if this is a manufacturing defect which made it through their quality control or what???  Will be returning this item forthwith, and plan to purchase -- in person -- at a local hardware store where I can inspect before buying.  One star.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good.
  

*by M***D on Reviewed in the United States on November 13, 2020*

I got this one because it had faster prime shipping than the actual mansfield flush seals available on amazon.  Fits great and is a perfect match for the Mansfield part.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works like a charm
  

*by D***R on Reviewed in the United States on March 7, 2020*

Replaced a rotting seal.  Took all of two minutes and now my toilet isn't constantly running!
