Overview
A 2 inch universal toilet flapper made in the United States, sized for the standard flush valve opening found in most residential toilet tanks.
Details are thin here since the listing gives little beyond country of origin, but the standard 2 inch, universal sizing puts it alongside the brand's other 2 inch parts, aimed at replacing a worn stock flapper rather than solving an unusual tank design.
- 2 inch universal fit
- Made in USA
- High purchase volume on Amazon
- Ultra high performance branding from Korky
Who it's for
Homeowners with a standard 2 inch flush valve toilet looking for a simple replacement without extra features like a water-saving dial.
Pros and cons
- Fits the common 2 inch flush valve standard
- Made in the United States
- Listing provides very little spec detail
- No adjustable dial mentioned
Performance notes
As a universal 2 inch part, it's meant to seal the standard flush valve opening shared by most residential toilets rather than adjust to a range of tank sizes.
