Mansfield 630-0030 Flush Valve Seal

After two tries with non Mansfield flush valve seals I discovered that I could get an actual Mansfield part. Although I had to adjust it after installation, it works perfectly. FYI - make sure the seal can be turned freely after installation. Bottom line - yes the flush valve seal costs more, but it works the first time rather than force you to buy and return inferior products.

Perfect part

Works so much better better than the off brands at Home Depot and lowes
