Overview
Korky makes this red rubber flapper in a two inch universal size, sold as a single piece. The name calls it ultra high performance, though the listing offers no figures to back that up.
A common valve size and a five year warranty make it a straightforward replacement. The limitation is the lack of any fit list or flush volume detail.
Who it's for
A running toilet with a two inch flush valve is the situation. Shoppers with other valve sizes, or who want a flapper with an adjustable water dial, should look at a different model.
Pros and cons
- Universal two inch size
- Five year warranty
- Fit list not given
- Flush volume not stated
- No adjustment dial listed
Performance notes
The flapper seals the valve opening with a rubber seat, so a clean seat and straight alignment matter. When the flapper wears or hardens, water leaks into the bowl. The listing does not describe the float or timing.
