Mostly five years. Korky's universal 2X Long Life models carry 10 years: 2017 for 2 in valves, 3070 for 3 in.
Kohler and TOTO fit families carry 5 years. A family label cannot promise every-toilet compatibility.

With no preferences selected: Korky 2011 2-Inch Flapper for Kohler Hinge is one option to compare.
Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.
Source dates appear with each link below. A source date does not confirm today's price or stock.
Korky's Kohler Shark Fin replacement is for a 2 in flush-valve opening, while its Genuine TOTO flapper is for a 3 in opening. The comparison covers those opening diameters, but matching diameter alone does not confirm the hinge, attachment or toilet fit.
Find your toilet's replacement instructions before choosing between a named family and a Universal label. The Universal label is a maker fit description, not permission to skip that check. Korky's fit information is the basis for the choices here, rather than flush-performance measurements.
Part references resolve look-alike replacements
Korky supplies replacement-part references for 3 flappers here: the Kohler Shark Fin, Kohler Rialto Float and TOTO Blue options. Use the reference together with the named toilet family. A missing reference on the Kohler Hinge version should not be borrowed from the Shark Fin or Rialto models.
Rubber material alone cannot resolve attachment differences. Compare the part that your toilet calls for, including any float or hinge arrangement, before treating similar-looking flappers as interchangeable.
Adjustment instructions matter more than the warranty length
Warranty terms run from 5 to 10 years, even though all 10 flappers use rubber. The longer warranty is a coverage distinction; it does not tell you how to adjust flush timing or attach the chain.
Follow your selected flapper's installation directions for adjustment and chain setup. For the fit questions left unanswered by material and warranty duration, use the toilet family and part reference.
Before you buy
Which flappers name the part they replace?
Three do. The Shark Fin 2012 replaces Kohler 84138, 84314, 85655 and 89825, the Rialto 2010 replaces Kohler 83064, and the blue 2022 replaces TOTO's THU140S. The Kohler Hinge 2011, the Genuine TOTO 2023 and the five universal flappers give no part number, so go by your toilet's parts list. Valve size alone doesn't settle fit either. Both TOTO flappers fit 3 in flush valves; Kohler Shark Fin, Rialto and Hinge replacements fit 2 in valves.
What are these flappers made of?
All ten are rubber. Korky names Chlorazone II rubber for the two 2X Long Life models, red rubber for six others, flexible rubber for the Genuine TOTO 2023 and blue rubber for the 2022.
Can a flush seal or tank ball stand in for a flapper?
This page covers flappers only. If your toilet uses a seal, a tank ball or another flush mechanism, identify it from the toilet maker's parts lookup first. Then follow Korky's fit and adjustment instructions, especially on a one-piece toilet or a maker's own flush valve design.
