Korky 100BP Flapper Rubber Stainless Steel Toilet Accessory

Direct Replacement Flapper

The Korky 100BP flapper fits most standard toilets and serves as a straightforward replacement part for worn seals. Homeowners and maintenance staff can install it without specialised tools, making it practical for quick repairs. It is not suited for buyers who need a universal repair kit with multiple seal sizes or an adjustable flush valve.

Material Limits and Compatibility

The flapper combines rubber with stainless steel components and uses a standard chain connection to the flush lever. Its regular type design follows common dimensions, so it works with typical two-inch flush valve openings found in residential fixtures. Installers should verify the existing valve seat condition, because a damaged or non-standard seat will prevent a reliable seal regardless of the flapper used.

Build Quality and Daily Use

The stainless steel reinforcement resists corrosion from tank water and cleaning agents, while the red rubber maintains flexibility over repeated cycles. The included chain connects directly to the flush handle arm, so no extra linkages are required. Routine inspection is simple — lift the tank lid and check that the flapper seats cleanly and the chain has minimal slack.
