Overview
A 2 inch universal toilet flapper made with Korky's proprietary Chlorazone II rubber, rated to last twice as long as standard rubber and adjustable across four common flush volumes.
This sits above Korky's standard 2 inch flapper as the long-life version, using a red rubber compound the brand says resists chlorine, bacteria and hard or well water better than typical flapper rubber. The adjustable design is meant to match the original flush setting on the tank rather than needing to be dialed in from scratch.
- 2x longer-life rubber compound
- Fits American Standard, Kohler, TOTO and more
- Adjustable across 1.28 to 5 gpf
- Resists chlorine, bacteria and hard water
Who it's for
Owners of a standard 2 inch flush valve toilet, including American Standard, Kohler or TOTO models, who want a longer-lasting part than a basic flapper, especially in homes with hard or well water.
Pros and cons
- Chlorazone II rubber rated 2x longer life
- Adjusts to match original flush setting
- Works across 1.28 to 5 gpf tanks
- Made in the USA
- 2 inch fit only
Performance notes
The Chlorazone II compound is formulated specifically against chlorine, bacteria and mineral-heavy water, the conditions that typically harden or crack rubber flappers within a year or two. Its adjustable settings cover 1.28, 1.6, 3.5 and 5 gallon per flush tanks, so it can be tuned back to the toilet's original flush amount instead of over or under flushing.
