Overview
Owners of older one-piece Kohler toilets get a factory replacement flapper with its chain, made to restore the original seal. It suits models from Pillow Talk to Laureate on the compatibility list.
Including the chain means one part fixes a running toilet. Corrosion resistance helps it last. Fit is limited to listed models.
Who it's for
Homes with vintage Kohler one-piece toilets suit the part. Newer models need a current flapper.
Pros and cons
- Genuine Kohler part
- Long compatibility list
- One year limited warranty
- Not a universal fit
- Only for older models
Performance notes
A flapper matched to the valve size seals flat, ending phantom refills. Chain slack controls how long it stays open, which affects flush strength. Corrosion resistant material slows wear.
