Overview
A blue rubber flapper is the seal at the heart of this Mansfield replacement, closing over the flush valve to stop tank water leaking into the bowl. It fits in place by hand with no tools.
Homeowners chasing a running toilet get a simple rubber flapper sized for larger flush valves. The listing claims both universal fit and two valve sizes, so check that your flush valve matches before buying.
Who it's for
Toilets that run or refill on their own suit a fresh flapper. Owners of toilets with unusual flush systems should confirm fit first.

Performance notes
