Replacement seal for Kohler flush valves

The Kohler K-1131496 is a plastic flush valve seal designed to restore proper sealing inside compatible Kohler flush valve assemblies. It is intended for maintenance professionals and facility managers who need a direct-fit component to stop water loss through a worn or degraded seal.

Upgrades from deteriorated original seals

This part replaces an original seal that has become brittle, cracked or misshapen after extended service. The jump is worth it when a toilet exhibits continuous running water, phantom flushes or an incomplete flush cycle caused by seal failure rather than by debris or misalignment.

Maintains seal integrity under constant water

The plastic material resists chlorine and mineral exposure so the sealing surface stays flexible during continuous immersion. It holds its shape through repeated actuation cycles without permanent compression set, preventing the slow leaks that develop when softer materials collapse over time.
